(written from a Production point of view)
Carey Loftin (31 January 1914 – 4 March 1997; age 83) was a stunt performer and stunt driver for films and television who was an uncredited truck driver in the Star Trek: The Original Series episode "The City on the Edge of Forever".
Loftin was born in Blountstown, Florida. His stunt credits span six decades and over a hundred films and television shows. He also occasionally appeared in the projects for which he performed stunts, usually in the role of a driver of an automobile of some kind. Perhaps the most notable of the latter was the (mostly) unseen maniacal truck driver who chased down Dennis Weaver in Steven Spielberg's acclaimed 1971 television movie Duel, which was written by Richard Matheson and also featured Gene Dynarski and Charles Seel. He was also the stunt coordinator for this project.
Loftin also served as stunt coordinator on a number of films, including 20,000 Leagues Under the Sea, THX 1138, Walking Tall, The Sugarland Express, The Deer Hunter, The China Syndrome, and The Dead Zone. He has also performed stunts for such acclaimed and popular films as Rebel Without a Cause, Spartacus, Patton, The French Connection, and The Goonies. His skills as a stunt driver especially came to use for films such as It's a Mad, Mad, Mad, Mad World, The Great Race, Bullitt (for which he participated in the now legendary car chase scene), The French Connection (working on the film's famous car chase), 1972's The Getaway, Brian De Palma's Blow Out, and Days of Thunder.
After retiring in 1990 at age 76, Loftin passed away in 1997, aged 83, in Huntington Beach, California. His final stunt work was for Clint Eastwood's film The Rookie.
