John Cason on AllMovie

Mean-looking John Lacy Cason was one of those unsung Hollywood heroes: a stuntman. A former professional prizefighter (hence his battered-looking nose), Cason was, according to his fellow stunt people, Pierce Lyden, "one of the toughest men in the business." He had arrived in Hollywood in the late '30s and began receiving billing in 1941, always playing henchmen. Nicknamed "Lefty" due to a fierce left-handed hook, Cason appeared in scores of B-Westerns in the '40s and guest starred on nearly all the television oaters of the following decade. He died in a road accident near Santa Barbara, CA, shortly after finishing an episode of Wagon Train.
