In 1958, Rickles made his film debut in a serious part in Run Silent, Run Deep with Clark Gable and Burt Lancaster. Throughout the 1960s, he often appeared on television in sitcoms and dramatic series. Rickles guest-starred in Get Smart as Sid, an old war buddy of Max's, who comes to stay with him. In an episode of Run for Your Life, Rickles portrayed a distressed comedian whose act culminates in him strangling a patron while imploring the patron to "Laugh!" Rickles took a dramatic turn in the low-budget Roger Corman science-fiction/horror film X: The Man with the X-Ray Eyes as a carnival barker out to exploit the title character (portrayed by Ray Milland).
