This extra character was played by an unknown performer. Apparently this crewperson remained for Kirk's command, even though the scene where he appeared in "The Corbomite Maneuver" was stock footage from the pilot episodes (as evidenced by his older-style uniform).
Bridge crewman 3
This Crewman exited the bridge just before the Enterprise picked up the distress signal (TOS: "The Cage")
An enlisted crewwoman in a beige uniform sat at a station to the right of the viewscreen. Captain Pike and CPO Garrison checked the SS Columbia follow-up message that printed out of her console. (TOS: "The Cage")
This extra character was played by an unknown performer. Her lack of rank insignia determines she was not an officer or chief. The function of her station, located between the viewscreen and Spock's station, was never alluded to, although it seemed to include various library computer functions and controls later associated with the science station.
This Engineer served aboard the Enterprise in 2254. He was operating the engineering station on the bridge when the Enterprise picked up the distress singnal. (TOS: "The Cage")
The geologist was played by Ed Madden, who later portrayed the technician Fisher in TOS: "The Enemy Within". Sources, including the Star Trek Magazine, have listed this officer's name as Fisher. This crewman wore the insignia of an officer on his sleeves, although the exact grade is unclear.
This extra character had no lines and was played by an uncredited performer. His appearance is the first rare occurrence of a 23rd centuryHuman wearing glasses, albeit briefly, in TOS. The next time glasses would be mentioned is Star Trek II: The Wrath of Khan, where it is implied that wearing corrective eyewear is rare because of vision-supporting drugs and treatments.
This Nurse aboard the Enterprise assisted DoctorMcCoy and NurseChapel to stabilize Kirk's body after Sargon had been believed to have been killed while inside it. She was also worried about how they would return Kirk's mind to his body, and how long the life support systems could keep his body alive without him. (TOS: "Return to Tomorrow")
She is one of the few medical personnel (besides Nurse Chapel) to wear the 'Red Cross' Enterpriseassignment patch.
Played by John Bellah. This person might be named "Harrison", because recordings of Bellah's voice laughing were dubbed in when McCoy tried unsuccessfully to contact TechnicianHarrison in the biopsy lab.
This officer was also present at Kirk's funeral service after the captain was presumed killed aboard the USS Defiant. (TOS: "The Tholian Web")
The appearance of a full Commander, outside of the regular cadre of permanent characters, is slightly unusual since the rank is normally held by senior department heads on a starship and would therefore be a somewhat important person on board. Such a person would also outrank such major characters like McCoy and Montgomery Scott. In any case, in the funeral appearance, this man could be seen wearing no rank insignia on his sleeves.
In 2268, this junior engineer was ordered by Montgomery Scott to repair a power relay (with a trident scanner) but was surprised to find two other officers (actually Miles O'Brien and Julian Bashir from the 24th century) already working on it. The two officers quietly allowed the engineer to take over as it became clear they had no idea what they were doing. Fortunately, he easily accepted Bashir's cover story - that he was doing a study on work-related stress, with O'Brien as his overworked, stressed-out patient - and agreed not to mention the incident, adding that he hoped O'Brien felt better. (DS9: "Trials and Tribble-ations")
This male operations division yeoman was under Leonard McCoy's care in sickbay in 2270.
McCoy informed the yeoman that he was going to be getting a few days' bed rest, for an unknown injury or ailment, despite the fact that the doctor didn't think he deserved it. Before the yeoman had a chance to acknowledge his prescription, he was startled by McCoy's sudden abduction from the ship by Kukulkan. (TAS: "How Sharper Than a Serpent's Tooth")
"The Trouble with Tribbles" writer David Gerrold played this unnamed, uncredited extra. He had reportedly written a cameo for himself (as Mr. Freeman) in that original, but was unable to be included in the filming. With new footage being filmed taking place in that episode almost thirty years later, Gerrold got to rectify that mistake playing a redshirt. He did have other Star Trek appearances in the interim (see Command division crewmember below).
These two unnamed Operations Division Security Guards were to beam down to Triacus. Unknown to them The Enterprise had left orbit. Vinci beamed both crewmen into where he thought Triacus was and they were both killed.
In 2268, this bulky male security officer (pictured, left) was one of several called in to break up a fight which had broken out between Enterprise officers and Klingon officers from the IKS Gr'oth. He ended up arresting Miles O'Brien. (DS9: "Trials and Tribble-ations")
Security lieutenant at K-7
In 2268, this male security officer (pictured, right), smaller than his counterpart above, was one of several called in to break up a fight which had broken out between Enterprise officers and Klingon officers from the IKS Gr'oth. He ended up arresting Julian Bashir. (DS9: "Trials and Tribble-ations")
Security lieutenants; Nomad victims #1 and #2
These two lieutenants were given the duty of escorting Nomad to the brig and guarding it. They were subsequently killed by the probe after it escaped and began roaming freely through the corridors of the ship. (TOS: "The Changeling")
Security lieutenant; Nomad victim #3
This lieutenant, along with Carlisle, was given the duty of replacing the above two guards escorting Nomad. Both this lieutenant and Carlisle were subsequently killed by the probe. (TOS: "The Changeling")
This individual was actually a caricature of the episode's writer, David Gerrold, that was added to the episode by animators as an in-joke. According to the novelization of the episode by Alan Dean Foster, this individual was named "Hacker," a name which Gerrold later found insulting.
Operations division table attendant
Female crewmember with red hair who helped dispense dinner when Enterprise officers were privileged to dine with the 20th century despot Khan Noonien Singh. She was later captured and seated in a prisoner's row with Brent, Hadley and others, forced to watch Khan's murderous spectacle on the viewscreen.
Command division table attendant
Brunette crewwoman who also helped serve dinner, she later escorted Khan to Lt. Marla McGivers' quarters. She was also captured when Khan took the vessel. (TOS: "Space Seed")
The chef of the ship's galley was in charge of reconstituting food and distributing them via the food slots.
All 170 crewmembers were played by extras, production staff members, and fans and most of them received no on-screen credit for their appearances. They were cast by a cattle call, organized by Bjo Trimble and had to fullfill these special requests: "aged between 20 and 40, men from 5'8" to 6'2", sizes 40-42, and women from 5'6" to 5'8', sizes 8-10"
The crewman, played by writer David Gerrold was identified in the non-canon novel "Ex Machina" as Ensign Gerry Auberson, a relief communications officer, JoAnn Christy's Vulcan officer as security technician T'Hesh, and Scott Dweck's Vulcan officer as Nurse Spanla.
This unnamed character, played by Billy Van Zandt, was identified as Alien Ensign in the script, and Alien Boy in the end credits.
According to Van Zandt, he was working at the Internal Security station. His single line of dialog with Uhura, about Decker's demotion, was not used in the theatrical print of the film, but was restored for the premiere television broadcast (ie. the "Special Longer Version" on the videocassette re-release), and for the "Director's Edition" on DVD. In issues of the Marvel/Paramount comic seriesStar Trek: Untold Voyages he was identified as Ensign Omal. In the Pocket novel Ex Machina, he was identified as Ensign Vaylin Zaand.
The Saurian was played by uncredited fan extra Cedric Taporco. The patches on this Saurian's uniform have a red backing, in the 2270s uniforms this signified an engineer. In the novel Ex Machina he was identified as Petty Officer second class R'trikahi.
These trainee crewmembers served aboard the Enterprise during its training simulation and later during the battle with Khan Noonien Singh. Some of them died during the explosions aboard the ship and in the torpedo launch bay. (Star Trek II: The Wrath of Khan)
