Bromberg made his screen debut in 1936 under contract to Twentieth Century-Fox. The versatile actor played a wide variety of roles ranging from a ruthless New York newspaper editor (in Charlie Chan on Broadway) to a despotic Arabian sheik (in Mr. Moto Takes a Chance) to the Alcade of Los Angeles (opposite Tyrone Power in The Mark of Zorro). Although he spoke with no trace of an accent, he was often called upon to play humble immigrants of various nationalities. When Warner Oland, the actor who played Charlie Chan, died in 1938, Fox considered Bromberg as a replacement, but the role ultimately went to Sidney Toler. Fox began loaning Bromberg to other studios in 1939 and finally dropped him from the roster in 1941. He kept working for various producers, including a stint at Universal Pictures in the mid-1940s; his employment there came to an abrupt halt when a change in management did away with all low-budget productions.
