Thomas "Tom" Lee Lupo is a stuntman, stunt actor, and stunt coordinator who played a security guard in the Star Trek: The Original Series first season episodes "The Alternative Factor", "The Menagerie, Part I" and "The Menagerie, Part II". He filmed his scenes for "The Alternative Factor" on Thursday 17 November 1966 at Desilu Stage 9 and on Wednesday 23 November 1966 at Vasquez Rocks Natural Area Park.
With a minimal list of acting credits, Lupos has had a long career as a stuntman and stunt coordinator, working in films such as Hooper, Batman & Robin and The Scorpion King and television shows such as Buck Rogers in the 25th Century and Magnum, P.I.. He has spent a great deal of his career as Tom Selleck's stunt double in various films and on TV. He is also the father of stuntwoman Diana R. Lupo.
His acting credits include the made-for-television movie Samurai (1979, with Walt Davis, Don Keefer, Greg Barnett, Johnny Haymer, Michael Pataki, and Bob Minor), and movies like Rocky III (1982, also with Bob Minor, and Michael Westmore doing makeup). His only non-Trek TV guest spot was in Tour of Duty (1988), with Robert Ito and Olivia d'Abo.
In 1980 he did stunt work in Hanger 18, written and directed by James L. Conway and featuring Bill Zuckert, Alan Gibbs, William Schallert and Joseph Campanella. The movie was later used in an early episode of Mystery Science Theater 3000.
