After several years as a radio Juvenile, he was cast as Tommy Gordon in the 1935 Broadway production of Sidney Kingsley's Dead End and traveled to Hollywood with the rest of the Dead End Kids when Samuel Goldwyn produced a film version of the play in 1937. Usually called Tommy in the films, he had the recurring role of a gang leader in a series of films that featured the Dead End Kids, later billed Little Tough Guys. In his later years, he claimed that he was paid more than the other Dead End actors, which had contributed to bad feelings in the group, and that he was tired of the name "Dead End Kids". He played with James Cagney in Angels with Dirty Faces (1938), and he also played the bully Flashman, speaking with an English accent, in the 1940 film Tom Brown's School Days opposite Cedric Hardwicke and Freddie Bartholomew.
