Mechanical engineer Lt. John Harkness (Gary Cooper) is given his first sea duty as captain of a small ship with an experimental new steam engine. Nicknamed the "USS Teakettle", the ship is soon the laughing stock of the Navy for its frequent breakdowns and the misadventures of its motley crew.
The comedy is sitcom-level routine, there are no real surprises in the story, and the romantic subplot involving Cooper and Jane Greer is pointless and clearly thrown in to add a woman to the cast. What makes this movie somewhat memorable is the terrific supporting cast of notables both past and future. Ed Begley, Ray Collins, and John McIntire are all good as the old guard C. O.'s, while youthful Eddie Albert, Richard Erdman, and Jack Webb make an impression as the ship's novice officers. Harvey Lembeck, Lee Marvin, Jack Warden, and Charles Bronson all make their movie debuts, and each get a moment or two in the spotlight. Bronson naturally has several shirtless scenes, and one memorable bit has him losing a boxing match to Jack Webb! Lembeck is the ship wiseacre, while Jack Warden is loud and exasperated. Lee Marvin, with dark hair, plays the radioman named Lee. I can't call this movie very good, but those who enjoy Mister Roberts, McHale's Navy will probably enjoy it.
