Revealing mistake: In the final scene where Fonda and Holbrook are looking over the carrier at the crowds on the dock you can see that only the first rows of people are dressed in period clothes, the rest of the crowd are dressed as they would have been in 1976 when the film was made.
Continuity mistake: When Norma and Helen are in the salon, and they are talking about Carrie going to the prom with Tommy, Norma is getting a fancy hairdo done for the prom. But in the next gym scene, she has her plain braids and a cap on. (00:48:20)Hamster
Plot hole: Radl and Steiner discuss the entire scheme to kidnap Churchill on the Alderney docks - in full view and hearing of a number of civilians (who shouldn't be there, pace another posting), including local fishermen. Though the Germans banned all fishing activities in the Channel islands including Alderney in 1941, they were well aware that there was a flow of information from the island to military authorities in the mainland. Why would they be so stupid as to discuss a top secret military mission in public? In reality, they wouldn't even discuss it in front of their own men.
Visible crew/equipment: In the scene where Laura is being attacked in the desert, the camera swings wildly. During this swing, the entire crew becomes visable for a split second. You can see Clint Eastwood (who also starred in the film) sitting in his director's chair, wearing a white t-shirt and watching the filming closely. (01:19:54)
Continuity mistake: When the train take off from Nürnberg, the locomotive is on "backwards". A few seconds later is it rotated 180 degrees.
Other mistake: The chronology of dates on the teletype printer at the end of the film are not in the correct order. We see "March 13, 1975" followed by "January 3, 1975", which is then followed by two August 1974 dates.
Continuity mistake: In the masked ball scene, St. Ives grabs a party goer and steals his mask which you then see him putting on. It is a gold mask without any markings that covers most of his face, but a few moments later when St. Ives dances with Flora, he is wearing a much smaller gold mask with black decorative markings.
Factual error: About 3/4 into the movie, in the scene where Woody is looking for a place to sleep, he comes upon this other man in a bunk. The guy in the bunk asks Woody if he wants to share his blanket with him because it is cold. Arlo does. In the next scene, outside, it shows the steam locomotive, and to the left of the steamer is a diesel locomotive. It is a Western Pacific GE logo. The movie is 1936 and WP diesels didn't show up till 1953. I was there.Engineer DC Kizer
Factual error: When a Rear Admiral and Captain are walking together, the Captain's epaulets are the wrong way round. A cardinal sin in the Navy. (01:30:00)
Continuity mistake: When the sniper starts shooting at the audience, at one point he hits a guy in the press sector. However the blood splatter at the victim's shirt appears yet before the bullet actually breaks the window.
