Stay Hungry is a 1976 American comedy-drama film by director Bob Rafelson from a screenplay by Charles Gaines (adapted from his 1972 novel of the same name).

The story centers on a young scion from Birmingham, Alabama, played by Jeff Bridges, who gets involved in a shady real-estate deal. In order to close the deal, he needs to buy a gym building to complete a multi-parcel lot. He becomes romantically interested in the gym's receptionist (Sally Field) and drawn to the carefree lifestyle of the Austrian bodybuilder Joe Santo (Arnold Schwarzenegger), who is training there for the Mr. Universe competition.

Schwarzenegger won a Golden Globe for Best Acting Debut in a Motion Picture, but it was not his true debut role; he had played Hercules (as Arnold Strong) in the 1970 film Hercules in New York, a gangster's henchman in Robert Altman's 1973 film The Long Goodbye, and a masseur in the 1974 television movie Happy Anniversary and Goodbye.
