MISTER ROBERTS stars Henry Fonda as Lt. Doug Roberts, chief cargo officer of the supply ship "Reluctant." WW2 is in its last few months, and Roberts is itching for combat duty. But the Reluctant's surly, despotic captain (James Cagney), anxious to use Roberts to expedite his own promotion, refuses to sign any of Roberts' transfer requests. Helping to brighten Mister Roberts' humdrum existence are his best friends, Ensign Frank Pulver (Jack Lemmon, in an Oscar-winning performance) and the ship's philosophical doctor (William Powell, in his final film appearance). Most of the laughs are provided by Pulver, officer "in charge of laundry and morale." When he isn't wheeling and dealing to bring a bevy of beautiful nurses on board the Reluctant, Pulver is concocting elaborate schemes to avenge himself against the Captain -- even though he's spent 14 months on the Reluctant without ever meeting his nemesis.
