Ralph Meeker was an American film, stage, and television actor. He first rose to prominence for his roles in the Broadway productions of Mister Roberts (1948–1951) and Picnic (1953), the former of which earned him a Theatre World Award for his performance. In film, Meeker is perhaps best known for his portrayal of Mike Hammer in Robert Aldrich's 1955 Kiss Me Deadly.

Mister Roberts is a 1948 play based on the 1946 Thomas Heggen novel of the same name.
