Continuity mistake: During the scene when Wally gets hit by the soldier in the cafe, and Wally bumps into another soldier, causing him to go into a cake, take notice of how much cake is on him throughout the different camera shots. Also Pops (the owner) starts to wipe the cake off of the soldier's face. The amount of cake changes between shots. (00:09:20 - 00:10:15)RLN
Revealing mistake: When the Ferris Wheel at the theme park has broken from its mounting and is rolling down the pier, it appears to be rolling forward but rotating anti-clockwise when if it is rolling forward it should be rotating clockwise.
Trivia: The U-boat in 1941 was a mock-up made just for the film. It was the front half only and all scenes of the sub were shot on a sound stage water tank. The sub just rose up and down out of the water. They did have a model sub that floated in the same studio tank for the scenes with the amusement park and ferris wheel.Mark Bernhard
