Vincent "Vince" Paul Deadrick (8 August 1932 – 27 May 2017; age 84), also known as Vince Deadrick, Sr., was a stuntman, stunt actor, and stunt coordinator who appeared in several episodes of Star Trek: The Original Series and made an uncredited "cameo" appearance in an episode of Star Trek: Enterprise.
Deadrick filmed his scenes for "Balance of Terror" on Wednesday 27 July 1966 and Thursday 28 July 1966 at Desilu Stage 9, and his scenes for "What Are Little Girls Made Of?" on Friday 29 July 1966 at Stage 10. He filmed his stunt scenes for "Shore Leave" on Tuesday 25 October 1966 and Wednesday 26 October 1966 on location at Vasquez Rocks Natural Area Park, and his stunt scene for "The Doomsday Machine" on Thursday 22 June 1967 at Stage 9. He filmed his scenes for "The Apple" between Thursday 20 July 1967 and Monday 24 July 1967 at Stage 10, and his stunt scene for "Mirror, Mirror" on Thursday 27 July 1967 at Stage 9. He filmed his scene for "Is There in Truth No Beauty?" on Wednesday 24 July 1968, also at Stage 9.
Deadrick was the father of stuntman and Enterprise stunt coordinator Vince Deadrick, Jr.. In 2004 he visited his son on the set of Star Trek: Enterprise. It was a highlight on the set because he was one of only five performers (along with Majel Barrett Roddenberry, Clint Howard, Joseph Ruskin, and Jack Donner) who appeared on both the original series and Enterprise. Deadrick, Jr. asked his father to do a stunt in the episode being filmed and his father performed a small stunt part as an alien slave trader in "Borderland". He is the only stunt actor who appeared in both The Original Series and Enterprise.
Deadrick performed in films such as The Enemy Below (1957, with Theodore Bikel, Biff Elliot, and Lou Elias), Love with the Proper Stranger (1963), Dirty Harry (1971, starring Andrew Robinson), Beyond the Poseidon Adventure (1979), The Lady in Red (1979, with Louise Fletcher, Christopher Lloyd, and Dick Miller), The Beastmaster (1982), Spacehunter: Adventures in the Forbidden Zone (1983, with stunts by Tony Cecere, Ann Chatterton, Phil Chong, Joyce McNeal, and Beth Nufer), Beverly Hills Cop (1984), Commando (1985), The Golden Child (1986), Throw Momma from the Train (1987, with Kate Mulgrew, Raye Birk, and stunts by Dana Dru Evenson and Donna Garrett), The Dead Pool (1988, with stunts by Patricia Tallman), Ghostbusters II (1989), Total Recall (1990), Broken Arrow (1996), For Better or Worse (1996, starring Jason Alexander), Lethal Weapon 4 (1998), and Bedazzled (2000, with Aaron Lustig, Rudolf Martin, Baron Jay, and stunts by Brian Avery, Eddie Braun, Shawn Crowder, Phil Culotta, Robert Herron, Pat Romano, George Wilbur, Mark Chadwick, Anita Hart, and Tom Morga).
