Star Trek II: The Wrath of Khan
- See: Kim Cattrall
- Main article: Madlyn Rhue
Madlyn Rhue was originally planned to reprise her role as Lieutenant Marla McGivers in the film, having established that part in TOS: "Space Seed". Harve Bennett ended up writing the character out of the film's story, after learning that Rhue suffered from multiple sclerosis which bound her to a wheelchair. Bennett felt it would be unfair to recast the role.
Star Trek III: The Search for Spock
- Main article: Kirstie Alley
Kirsty Alley was offered the chance to reprise the role of Saavik in Star Trek III: The Search for Spock, but according to Alley, she was offered less money for that film than she was paid for Star Trek II and thus declined to return. According to Leonard Nimoy, Alley's talent agent demanded a salary that was higher than DeForest Kelley's after learning that Saavik was to have a large role in the film.  It was also reported that "Just before production began, negotiations with Kirstie Alley broke down. [...] The Los Angeles Times indicated the problem concerned money with Alley asking 10 times the salary she earned on Star Trek II. [...] Alley's representative, Michael Levine, agreed that the problem was financial, but refused further details." (Starlog #77, December 1983, p. 15)
After an intensive casting search, Nimoy opted instead to recast the role of Saavik, which was ultimately given to Robin Curtis.
In a later interview, Alley reported wanted to reprise the role, but Paramount wasn't willing to pay what she was asking, which according to Alley was "less money then they did for Star Trek II, so I figured they weren't very interested in me for Saavik." This, combined with the commitment of a co-starring role in the TV pilot Masquerade for ABC, forced Alley to bow out of the role. (Starlog #102, January 1986, p. 43)
Upon viewing The Search for Spock, Alley found the film an enjoyable but unnerving experience, as she came to the realization that of Curtis' as Saavik, "She wasn't me". Sympathizing with Curtis, however, Alley revealed that "I thought she was at a real disadvantage playing the role someone else established, especially with Star Trek, which has an enormous following. I think she did a fine job. I have no problem with what she was doing except that, when I saw the film, I said, 'She isn't Saavik. I am.'" (Starlog #102, January 1986, p, 43)

Star Trek IV: The Voyage Home
- Main article: Mariette Hartley
- Main article: Robert Hooks
Robert Hooks was due to reprise his role as Morrow in the film, but became unavailable for unknown reasons, and the character was replaced by Cartwright (played by Brock Peters). The revised final draft script specifies that Morrow was changed to Cartwright. 
Eddie Murphy, a popular actor and comedian who rose to stardom as a regular on Saturday Night Live (frequently appearing in tandem with Joe Piscopo - Charles Rocket was also in the cast his first season) and as the star of the films 48 Hrs and Beverly Hills Cop (both for Paramount Pictures), was initially rumored to appear in Star Trek IV: The Voyage Home either as himself or as a Murphy-like character.
Another casting controversy sparked by press speculation concerns a possible starring (or cameo) role for comedian Eddie Murphy in Star Trek IV. "It's too premature to discuss that," Nimoy maintains. "There has been much conjecture about Murphy since Beverly Hills Cop. The press has been very curious about what he will do next. They know he has a multi-picture deal with Paramount. They know he is a big Star Trek fan. They know Trek IV is in preparation at Paramount. So, it isn't surprising that rumor would pop up. And when I started talking about the film being lighter in tone, some people put two and two together."
Indeed, many Trek fans have already reached that conclusion, and have vociferously voice their opposition to the idea. They fear the inappropriate casting of Murphy could torpedo Trek IV as irreparably as the selection of Richard Pryor sabotaged Superman III.
Although unwilling to substantiate the speculation, Nimoy still refuses to publicly dismiss the notion of incorporating the unorthodox antics of the madcap Murphy into the sedate atmosphere of the Star Trek environment. "Why should I?," he asks, not entirely rhetorically. "What would be gained? Why should I try to reassure the fans who are worried about it? That would mean I was letting them dictate to me." [...] "I've been through this before." [...] "In other words, we are professional people doing a professional job. If we decide that Eddie Murphy should be in Trek IV, then the fans will have to trust us. Let us do our work."
Shortly before the release of the film, it was noted that "at the other end of the soundstage from Star Trek IV: The Voyage Home is a large, sewer set from The Golden Child, Eddie Murphy's new fantasy adventure. Murphy's proximity is a reminder that he was once rumored to have a role in the new Trek film. It was, however, only a small part with Murphy unrecognizably made up as a Klingon official–a role that was instead filled by character actor John Schuck." (Starlog #111, October 1986, p. 40; Starlog #138, p. 30)
Years later, it was confirmed that Murphy had expressed interest in the part and early scripts were written with Murphy in mind for the role of a major character, an eccentric professor who believed that aliens exist, who ultimately became Gillian Taylor. Ultimately a negative writing campaign coupled with story issues prompted the writers to drop the idea, and Murphy moved on to other projects. "I'm a Trekkie. I've always loved Star Trek and have wanted to do one of the films," says Murphy. "The script was developed, but we eventually dropped the idea. [The] Golden Child came along and I decided to do that film instead ... In retrospect, I might have been better off doing Star Trek IV." The character was ultimately rewritten as a woman and the part went to Catherine Hicks. (Starlog, October 1987, p. 8; The Trek 25th Anniversary Celebration; Trekworld, June 1999)
Since then, Murphy has continued a successful career in film, starring in such hits as Coming to America, The Nutty Professor, Doctor Dolittle, Daddy Day Care, and the Shrek films. In 2006 he received his first Academy Award nomination for his supporting role in Dreamgirls.
Susan Sarandon was one of "several other actresses [who] were considered for the role of Dr. Taylor [...] but Hicks fought through four auditions to land the part." At the time she was known for her work in the Rocky Horror Picture Show. (Starlog, March 1987, p. 39)
Star Trek V: The Final Frontier
- See: Kim Cattrall
Sean Connery was a widely-popular Scottish actor who is perhaps best known for being the first to play James Bond in feature films. He portrayed Bond in seven films, beginning with Dr. No in 1962 and ending with Never Say Never Again (with Bernie Casey) in 1983. He has also acquired great fame as a movie star for his roles in films such as Alfred Hitchcock's Marnie (1964, with Meg Wyllie), The Longest Day (1962, with Jeffrey Hunter, Richard Beymer, and John Crawford), The Man Who Would Be King (1975, co-starring Christopher Plummer), A Bridge Too Far (1977), Highlander (1986, with Clancy Brown), Indiana Jones and the Last Crusade (1989, with John Rhys-Davies), The Hunt for Red October (1990, with Gates McFadden, Daniel Davis, Boris Krutonog, Ronald Guttman, Timothy Carhart, Ned Vaughn, and music by Basil Poledouris), The Rock (1996, with Tony Todd), Entrapment (1999), and Finding Forrester (2000, with F. Murray Abraham and Michael Nouri). He also won an Academy Award for his supporting role in 1987's The Untouchables.
William Shatner originally wanted Sean Connery to play the role of Sybok in Star Trek V: The Final Frontier. Shatner had tremendous respect for Connery's acting talents, and knew that his presence would be a great bonus in that the film would draw a foreign box office business. Before Paramount could close the deal with him, Connery accepted a role in Indiana Jones and the Last Crusade, which was scheduled to film at the same time as Star Trek V. Shatner was deeply disappointed to learn of Connery's unavailability. Despite this, the writers kept the reference to Connery – Sha Ka Ree – in the film.
In Shatner's search for Connery's replacement, he looked at other foreign actors which might bring in overseas business. "We considered several people," he said, "and were especially intrigued by one well-known Swedish actor (Max von Sydow) who I consider very talented. But when we found out how expensive he was, that idea quickly flew out the window."
Shatner and Harve Bennett went back to the drawing board, and drew up a list of possible candidates for the role and began looking at the roles each had portrayed. One actor on the list, Laurence Luckinbill, caught Shatner's eye from his role as Lyndon B. Johnson in the PBS presentation "Lyndon Johnson", and he was eventually cast in Connery's place. (Captain's Log: William Shatner's Personal Account of the Making of Star Trek V: The Final Frontier, Star Trek Encyclopedia (? ed., p. ?))
McLish is a famous female bodybuilder and former Ms. Olympia who retired in 1984. She has acted in several movies such as Getting Physical (1984) alongside Spice Williams-Crosby and TNG guest actor Earl Boen and Raven Hawk (1996) with John de Lancie, Michael Champion, Ed Lauter, John Fleck, and Nicholas Guest, and published several books as well as many fitness instruction videos.
Max von Sydow
Max von Sydow was a well-known Swedish actor who was considered for the role of Sybok when Sean Connery proved unavailable. According to William Shatner, the idea of using von Sydow "quickly flew out the window" when he discovered how high his expected salary was compared to the remaining production budget. (Captain's Log: William Shatner's Personal Account of the Making of Star Trek V: The Final Frontier; Charting the Undiscovered Country: The Making of Trek VI)
Max von Sydow is known for his many collaborations with famed writer/director Ingmar Bergman during his early career, which included the acclaimed films Wild Strawberries (1957), The Seventh Seal (1957), The Magician (1958), The Virgin Spring (1960), and Through a Glass Darkly (1961). Perhaps von Sydow's best-known American film role is that of Father Merrin in the 1973 horror film The Exorcist. He was received Golden Globe nominations for his work on both The Exorcist and the 1966 film Hawaii, and was nominated for an Academy Award for his performance in the 1987 Danish film Pelle the Conqueror.
By 1988, when he was being considered for a role in Star Trek V, von Sydow was no stranger to science fiction, having played Ming the Merciless in the 1980 film Flash Gordon. He also co-starred with Christopher Plummer in the 1984 sci-fi film Dreamscape and appeared as Dr. Kynes in David Lynch's 1984 film adaptation of Dune, which featured a number of future Star Trek alumni (Brad Dourif, Virginia Madsen, Dean Stockwell, and, most notably, Patrick Stewart). Since then, von Sydow's science fiction credits have included Judge Dredd (1995), Steven Spielberg's Minority Report (2002) and appeared as Lor San Tekka in J.J. Abrams' Star Wars: Episode VII - The Force Awakens. He also ventured into the fantasy genre, including the role of King Osric in 1982's Conan the Barbarian.
His many other, non-genre film credits include the 1975 thriller Three Days of the Condor, the 1986 comedy Hannah and Her Sisters, the 1993 horror film Needful Things, and the dramas Awakenings (1990) and Snow Falling on Cedars (1999). More recent credits include Rush Hour 3 (2007) and The Diving Bell and the Butterfly (2007).
Star Trek VI: The Undiscovered Country
- Main article: Kirstie Alley
Kirstie Alley was originally asked by director Nicholas Meyer to reprise her role as Saavik in the film, but her price was deemed to be too high. Other sources (most notably Meyer himself) say that she refused Meyer's requests because of weight problems, feeling she would look fat in a tight-fitting uniform. Finally Kim Cattrall was cast in the role, which was eventually reworked into the character of Valeris. (Star Trek VI: The Undiscovered Country (Special Edition) DVD audio commentary)
Most ironically, Cattrall was not available for the original part in Wrath of Khan, whereas it was Alley, who turned out to be unavailable for The Undiscovered Country. Alley's unavailability, was the reason why the character of Saavik was changed into that of Valeris, as Robin Curtis, who had also played the part of Saavik, had never been considered to reprise the role. (Cinefantastique, Vol. 22, No. 5, p. 31)
- Main article: Whoopi Goldberg
Whoopi Goldberg, eager to make a cameo appearance in the film, met with Nick Meyer to discuss the possibility of her appearing as a "Klingon princess" in Star Trek VI. This idea was vetoed by Leonard Nimoy, who feared that too many well known performers in the film's supporting cast might detract from the movie being the last to feature the regular TOS cast. Goldberg was also making recurring appearances as Guinan in Star Trek: The Next Generation. (The View from the Bridge, hardcover ed., p. 211)
- Main article: Jack Palance
Jack Palance was an American actor, originally approached to play Gorkon in Star Trek VI: The Undiscovered Country. He was scheduled to appear in the film City Slickers, which earned him an Academy Award, and David Warner was cast in the role instead. Palance appeared in many classic Hollywood films, including Shane (1953), which was briefly featured in DS9: "It's Only a Paper Moon". Elisha Cook also appeared in the film. Other films of Palance include Austerlitz (1960, with Orson Welles), Le mépris (1963), Chato's Land (1972), Batman (1989, with Tracey Walter), and Tango and Cash (1989, with Teri Hatcher, Marc Alaimo, and Michael J. Pollard).
Star Trek Generations
Two-times Academy Award-winning actor Marlon Brando was interested in playing Tolian Soran, and his representative contacted producer Rick Berman about the role. Berman was enthusiastic about having Brando on board, and contacted Paramount CEO Sherry Lansing about the possibility. However, Brando was asking for a very high salary, which Lansing was not ready to pay.
According to Berman, "It was numerous millions of dollars, much more than she had any interest in paying. This was also at a point when he was quite overweight, and it was an action-hero type of role. My feeling was, 'we're talking about Marlon Brando here!' But Sherry had remarkable experience in the motion picture business and said 'Brando's presence is not going to justify the expenditure'". 
Considered to be among the greatest actors of the 20th century, Brando rose to fame with his roles in films such as A Streetcar Named Desire (1951), Viva Zapata! (1952, with Arnold Moss), The Wild One (1953, with Carey Loftin, Sam Gilman, and K.L. Smith), and On the Waterfront (1954, with Nehemiah Persoff). His career continued with projects like The Fugitive Kind (1960), his directorial debut One Eyes Jacks (1961, with Elisha Cook), and Mutiny on the Bounty (1962, with Antoinette Bower, Michael Dugan, Torin Thatcher, and Paul Baxley).
In 1972, Brando played the iconic role of mafia boss Don Vito Corleone in The Godfather. Joe Lombardi served as special effects supervisor, and Paul Baxley as second unit director for the film. In his later career, Brando appeared as Jor-El in Superman (1978, edited by Stuart Baird), as Colonel Kurtz in Apocalypse Now (1979), and as the titular character in The Island of Dr. Moreau (1996, with Ron Perlman and Frank Welker).
- Main article: DeForest Kelley
DeForest Kelley was approached to appear as Leonard McCoy in the prologue sequence of Generations. He felt the part was rather just a cameo, and that the original characters made their exit well in Star Trek VI: The Undiscovered Country. The script was re-written to feature Pavel Chekov (Walter Koenig) instead.
- Main article: Leonard Nimoy
Leonard Nimoy was approached to appear as Spock in the prologue sequence of Star Trek Generations and direct the film, but declined the offer. As Nimoy explained, "There were five or six lines attributed to Spock [...] but it had nothing to do with Spock. They were not Spock-like in any way. I said to Rick Berman, 'You could distribute these lines to any one of the other characters and it wouldn't make any difference.' And that is exactly what he did. There was no Spock function in the script. I have always tried to make a contribution to these movies. There was no contribution to be made in that movie. It was just sort of 'let's get Nimoy in here too.' I said there is nothing here I can do so I said 'thanks, but I'll pass'."  He was replaced by Montgomery Scott (James Doohan) in the scene.
Star Trek: First Contact
- Main article: Avery Brooks
Tom Hanks is the two-time Academy Award–winning American actor, who was originally approached to play Zefram Cochrane in Star Trek: First Contact. Hanks, a self-admitted Trekkie, had to turn down the offer, as he was busy working on his directorial debut, That Thing You Do! (which featured Clint Howard).
Hanks built a long and successful career in film, working as an actor, producer, writer, and director. He started out in comedies, such as Splash (1984, with Charles Macaulay, Clint Howard, Bill Smitrovich and cinematography by Don Peterman), The Money Pit (1986, with Tzi Ma), and Big (1988, with Josh Clark), and also starred in Trek director Nicholas Meyer's 1985 film, Volunteers (with Clyde Kusatsu and music by James Horner). He turned to more serious roles in the early 1990s with such films as The Bonfire of Vanities (1990, with Kim Cattrall, Saul Rubinek, Kirsten Dunst, Jon Rashad Kamal, F. Murray Abraham, and Terry Farrell) and Sleepless in Seattle (1993).
His big break came with two roles which won him the Academy Award for Best Actor in two consecutive years: Philadelphia (1993, with Charles Napier) and Forrest Gump (1994). Since then, Hanks appeared in a variety of well-received movies, including Apollo 13 (1995, with Clint Howard, Max Grodénchik, Steve Rankin, and John Wheeler, and music by James Horner), Saving Private Ryan (1998, with Leland Orser and John de Lancie), You've Got Mail (1998), The Green Mile (1999, with James Cromwell and William Sadler), Cast Away (2000, with Michael Forest), Road to Perdition (2002), Catch Me If You Can (2002, with Thomas Kopache and Malachi Throne), The Terminal (2004, with Zoë Saldana), The Da Vinci Code (2006), and Charlie Wilson's War (2007). He also lent his voice to a number of animated productions, including Toy Story (1995) and its two sequels (which also featured Wallace Shawn and Kelsey Grammer), The Polar Express (2004), and Cars (2006, with Paul Dooley).

Walken is a highly accomplished actor, known for such films as Annie Hall (with Mark Lenard and John Glover), The Deer Hunter (co-starring John Savage), The Dead Zone (with Anthony Zerbe), A View to a Kill (with Walter Gotell), Batman Returns (with Vincent Schiavelli, Biff Yeager, Felix Silla and Anthony DeLongis), True Romance (with Christian Slater and Saul Rubinek), Pulp Fiction, and Catch Me If You Can (with Thomas Kopache, Jimmie F. Skaggs, J. Patrick McCormack, and Malachi Throne).
Star Trek Nemesis
James Marsters auditioned for the role of Shinzon in Star Trek Nemesis, but the role ultimately went to Tom Hardy. Actress Marina Sirtis believes Marsters would have been more suitable in the role. 
Marsters is best known for playing Spike on Buffy the Vampire Slayer and Angel and Captain John Hart on the Doctor Who spinoff Torchwood. He co-starred with Star Trek: Enterprise actress Jolene Blalock and TNG/DS9/VOY guest actor Tony Todd in the film Shadow Puppets and had a supporting role in the 2007 drama P.S. I Love You. In 2001, he played Charlemagne Bolivar in an episode of Gene Roddenberry's Andromeda. He also had a recurring role as Professor Fine/Brainiac in the CW series Smallville and also played the villain Piccolo in the live-action film adaptation of the popular anime series Dragonball.
Craig T. Nelson
Alan Rickman was rumored for the role of the Reman Viceroy in Star Trek Nemesis, succeeding the rumor of Nelson filling the role. Rickman had already played the Nimoy/Spock-inspired Alexander Dane/Dr. Lazarus (alien) primary character in Galaxy Quest, the 1999 insightful Star Trek satire.
Shanks is best known for playing Dr. Daniel Jackson on the long-running series Stargate SG-1, its direct-to-video spinoff films and television spin-off series. Shanks has also appeared on such shows as Smallville, Andromeda, and Burn Notice.
Star Trek (2009)
J.J. Abrams briefly considered adding a member of this Japanese band to the cast of the '09 movie after seeing them perform live. It never materialized. 
Academy Award-winning actor Adrien Brody was in talks to play Spock in Star Trek, the eleventh Trek film released in 2009. At first, his connection to the project was merely a rumor,  but Brody himself later confirmed that he had discussed playing Spock with the film's director, J.J. Abrams.  The role of Spock ultimately went to Zachary Quinto.
Brody had supporting roles in several popular films throughout the 1990s, including Steven Soderbergh's King of the Hill, Disney's baseball fantasy Angels in the Outfield (working with Christopher Lloyd and Neal McDonough), Terence Malick's The Thin Red Line, and Spike Lee's Summer of Sam (with Bebe Neuwirth and Mike Starr). He also played the leads in a number of smaller films, including 1998's Restaurant, 1999's Liberty Heights, and 2002's Dummy.
Brody won the 2002 Academy Award for Best Actor in a Leading Role for his portrayal of Polish Jewish musician Wladyslaw Szpilman in Roman Polanski's The Pianist. He has since starred in such films as M. Night Shyamalan's The Village, Peter Jackson's King Kong, Allen Coulter's Hollywoodland, Wes Anderson's The Darjeeling Limited, the adventure comedy The Brothers Bloom, and the biographical drama Cadillac Records (with Gabrielle Union).
Matt Damon is an American Academy Award-nominated actor and Academy Award-winning screenwriter who was approached to play James T. Kirk's father, George Kirk in Star Trek.  According to Abrams, Damon turned down the role for "most gracious and understandable and logical of reasons."  The role ultimately went to Chris Hemsworth.
Before this, Damon had long been rumored to be in the running for the role of James T. Kirk in the film. It was even rumored that he solicited William Shatner's aid in getting him signed up. Damon himself denied having been approached for the role, although he later told Sci-fi Wire that he would be interested in playing a young Captain Kirk if the script met with his satisfaction. In March 2007, Kurtzman, although not confirming that Damon would play Kirk, stated that he was "the hugest Matt Damon fan. If he became [Kirk], great."  In a subsequent interview with IGN, Damon stated that the filmmakers were looking for someone younger for the role.  Chris Pine was ultimately cast in the role.
Damon began acquiring fame in the 1990s with major roles in such films as School Ties (1992), Courage Under Fire (1996), and Saving Private Ryan (1998). He and best friend Ben Affleck won an Academy Award for their screenplay to the 1997 drama Good Will Hunting, for which Damon also received an Academy Award nomination for Best Actor in a Leading Role. Damon and Affleck later became executive producers on Project Greenlight, for which they received three Emmy Award nominations. Damon and Affleck have also worked together on several projects for director Kevin Smith, most notably the 1998 film Dogma.
In addition, Damon is known for his roles in two film franchises: he plays young thief Linus Caldwell in the Ocean's films (Ocean's Eleven in 2001, Ocean's Twelve in 2004, and Ocean's Thirteen in 2007), and also stars as amnesiac assassin Jason Bourne in the Bourne films (The Bourne Identity in 2002, The Bourne Supremacy in 2005, and The Bourne Ultimatum in 2007). Had he been cast in Star Trek, it would have marked his second film with Karl Urban, whom he worked with on The Bourne Supremacy. It also would have been his second movie photographed by Daniel Mindel, after the 2003 comedy, Stuck on You.
Damon's other films include The Talented Mr. Ripley (1999), The Legend of Bagger Vance (2000), The Brothers Grimm (2005), Syriana (2005, in which he acted alongside Star Trek: Deep Space Nine regular Alexander Siddig), Martin Scorsese's Academy Award-winning The Departed (2006, with Mark Rolston). He also lent his voice to such films as Titan A.E. (2000, along with Ron Perlman and Charles Rocket), Spirit: Stallion of the Cimarron (2002, with James Cromwell), and the English version of the Hayao Miyazaki film Ponyo.
Damon earned his second Academy Award in an acting category for his performance in Clint Eastwood's 2009 drama Invictus. He has since been seen in such films as Eastwood's Hereafter (2010), the Coen brothers-directed remake of True Grit (2010), the family drama We Bought a Zoo, and the hit 2011 sci-fi thrillers Contagion and The Adjustment Bureau. Damon also worked alongside Star Trek: Enterprise star Scott Bakula in two films directed by Steven Soderbergh: the 2009 comedy The Informant and the 2013 Liberace biopic Behind the Candelabra. In addition, Damon played the recurring role of airline pilot Carol Burnett on the NBC comedy series 30 Rock.
More recently, he appeared in the sci-fi action thriller Elysium (2013, featuring Faran Tahir), Terry Gilliam's The Zero Theorem (2013), George Clooney's ensemble drama The Monuments Men (2014), the science fiction film The Martian (2015), another Bourne sequel, Jason Bourne (2016), and the sci-fi satire Downsizing (2017).
Ricky Gervais is an English actor, comedian, producer, and director who turned down an unspecified role in Star Trek. He was approached by the film's director and producer, J.J. Abrams, whom Gervais previously worked with on an episode of Alias, but Gervais rejected a part in the film.

Michael Dorn played Worf and his grandfather in the previous films and television series, and was offered the part of "an officer – a soldier." He and his agent expressed interest, but "then time went by and we finally talked to them at maybe the end of January or February  and they said they had changed their mind." Dorn was unclear why, speculating "It could have been the casting people going 'Hey this would be a good idea' and they shot it up the road to JJ and he said 'No, we aren't going to do that.' But I don't know. It is nothing nefarious. Nothing mean. They changed their mind, so I don't worry about it."
