Mitchum then sought work as a film actor. An agent he knew from his work in theater got him an interview with Harry Sherman, the producer of United Artists' Hopalong Cassidy Western film series, which starred William Boyd. In June 1942, Mitchum began his film career with a part as a minor villain in Border Patrol, the first of seven Hopalong Cassidy films he made that were released in 1943. That year, he appeared in a total of 19 films. His first non-Western was Follow the Band, a musical at Universal, and he went uncredited as a soldier in The Human Comedy, a major MGM picture starring Mickey Rooney. Other films in which he played supporting parts included a Laurel and Hardy comedy, The Dancing Masters, and two war films starring Randolph Scott, Corvette K-225 and Gung Ho!. Harry Cohn offered him a studio contract after viewing his performance in Columbia's musical Doughboys in Ireland. Mitchum, however, declined the offer.
