Mister Roberts (1955)

Factual error: When Roberts makes a deal with the Captain, he demands that the Captain grant liberty to both sections (i.e., the entire crew), leaving only Roberts and one enlisted man aboard as the deck watch. All U.S. Navy ships must have enough personnel aboard at all times to get the ship underway immediately, if necessary, which is why the crew is divided into watch sections.

Lt. J.g. Douglas A. Roberts: Captain, you told me.
The Captain: Never mind what I told you. I'm telling you!.

Trivia: Thomas Heggen wrote the novel "Mister Roberts" based on his wartime experiences on two Navy cargo ships, U.S.S. Virgo (AKA-20) and U.S.S. Rotanin (AK-108). The Virgo was an attack cargo ship, designed for use in amphibious assaults, and saw quite a bit of action. In the movie, U.S.S. Hewell (AKL-14) was used as the fictional Reluctant. The Hewell was a light cargo ship, designed for coastal operations. A basic comparison of the three ships follows: Hewell/Reluctant: 176 feet long, 500 tons, 26 crew (not 62, as stated in the movie.) Rotanin: 441 feet long, 4000 tons, 206 crew Virgo: 460 feet long, 6500 tons, 404 crew.
