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.
Pvt. Ogden Johnson Jones: Real Japs?
Captain Wild Bill Kelso: Nah, wooden Japs, Cheetah. What do you think?
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.
