A hilarious and heartfelt military comedy-drama co-directed by John Ford and Mervyn LeRoy, Mister Roberts stars Henry Fonda as an officer who's yearning for battle but is stuck in the backwaters of World War II on a noncommissioned Navy ship run by the bullying Capt. Morton (James Cagney). Jack Lemmon enjoys a star-making turn as the freewheeling Ensign Pulver, and William Powell stars as the ship's doctor in his last screen role.
