Trivia: A (corrected) entry states that a USAAF B-17 'Flying Fortress' bomber is visible in the film. In fact in some prints produced for release in the US irrelevant stock footage of a B17 was randomly cut into the film to make it more acceptable to American audiences. This was a deliberate alteration of the film done very much against the wishes of the producer and director, and it explains the 'error' - the contributor has seen one of the non-canon US prints.
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.
