Continuity mistake: After giving a toast for Roy at the bar, Dick and another soldier are walking along the sidewalk when they hear a car honk behind them. As they turn, some navy sailors pass them by as they turn around. The camera cuts to a different angle and suddenly the people who passed them are gone, with others much further down the sidewalk.

Factual error: Admiral Yamamoto and Nagumo are in the back of the car about 30 minutes into the movie. As the camera pans outside, you can see the car is driving on the right side of the road. Japan drives on the left. (00:28:00)
Factual error: Only four B-26 bombers attacked the Japanese fleet, not the dozen shown in the movie.
Factual error: The TBD Devastator bombers at one point are shown armed with both torpedoes and bombs. While the Devastator could be armed with either torpedoes or bombs, it could not carry both at the same time. Furthermore the bombs are shown being fitted under the Devastator's wings, the Devastator had no hard-points under the wings in reality.
Other mistake: At the end, it states "Clarence Dickinson became a 'Real' Admiral..." instead of Rear Admiral. (02:04:17)
