Underworld is a 1937 gangster film directed by Oscar Micheaux, about a recent graduate from an all-black college who moves from the American South to Chicago and gets swept into the criminal underworld. The film was adapted from the short story "Chicago After Midnight" by Edna Mae Baker. Among its stars are Ethel Moses, a Micheaux regular, and Oscar Polk, best known for his appearance in Gone with the Wind two years later.
