Francis in the Navy is a 1955 American black-and-white comedy film from Universal-International, produced by Stanley Rubin and directed by Arthur Lubin.

Peter's insistence they have the wrong man lands him the psychiatric ward, despite pleas to the base's semi-addled Commander Hutch.

But Slicker is regarded as a champion athlete, and Peter has to take part in a boxing exhibition against the bruiser Bull Bostwick.

Peter is knocked out, despite Francis' effort to fix the fight (ringing the bell gong at odd times; greasing the opponent's shoes, etc.).

Peter's task is to drive a DUCK (amphibious vehicle) to a pre-arranged spot as a "vital supply delivery".

Donald O'Connor was reluctant to make the film but agreed to do one more at the request of his daughter[3] (in addition to a financial inducement from Universal studio head Edward Muhl).
