Jack Elam was an American film and television actor whose career spanned more than 40 years.  He grew up in difficult circumstances, moving from the households of relatives and father, stepmother and siblings after his mother passed away.  He attended Santa Monica Junior College in California, then worked as an accountant and later, he briefly was manager of the Bel Air Hotel.  Purportedly, he got his first movie job by trading his accounting services for a role.  His film debut was a role in "She Shoulda Said No!" (1949), an exploitation film about the vices of marijuana.  Elam quickly became one of the most memorable supporting players in Hollywood and became well-known for playing villains in western genre and gangster films.   He played up a near-demented screen persona, which was enhanced by a wandering left eye rendered sightless from a childhood fight.  Although he was a highly recognizable villain throughout most of his acting career, in later years he played more comedic roles, becoming more winsome, if still grizzled and slightly crazed.

Elam made five guest appearances in THE RIFLEMAN, portraying different characters in each episode.  He played Sim Groder in "Duel of Honor" (episode 7), Gavin Martin in "Tension" (episode 45), Gus Smith in "Shotgun Man" (episode 69), Gates in "The Knight Errant" (episode 117) and Russell, the Pool Shark, in "Shattered Idol" (episode 120).   In 1994, Elam was inducted into the Hall of Great Western Performers of the National Cowboy and Western Heritage Museum.
