James Howard Dunn, billed as Jimmy Dunn in his early career, was an American stage, film, and television actor, and vaudeville performer. The son of a New York stockbroker, he initially worked in his father's firm but was more interested in theater. He landed jobs as an extra in short films produced by Paramount Pictures in its Long Island studio, and also performed with several stock theater companies, culminating with playing the male lead in the 1929 Broadway musical Sweet Adeline. This performance attracted the attention of film studio executives, and in 1931, Fox Film signed him to a Hollywood contract.

Bad Girl is a 1931 American pre-Code drama film directed by Frank Borzage and starring Sally Eilers, James Dunn, and Minna Gombell. The screenplay was adapted by Edwin J. Burke from the 1928 novel by Viña Delmar and the 1930 play by Delmar and Brian Marlowe. The plot follows the courtship and marriage of two young, working-class people and the misunderstandings that result from their not having learned to trust and communicate with one another. The film propelled then-unknown actors Eilers and Dunn to stardom. It was nominated for three Academy Awards, including Best Picture, and won for Best Director and Best Adapted Screenplay.
