Revealing mistake: Halfway through the movie, Alta is swimming in the pond, supposedly nude. However, when she climbs out, she can be seen wearing a flesh-covered swimsuit. (00:45:15)
Suggested correction: Alta never said she was naked. She didn't know what a bathing suit was and Adams assumed she was naked.
Revealing mistake: In the scene out West with the buffalo, notice the car driving in the distant background.
Revealing mistake: When the parted Red Sea comes together, if you look behind Pharaoh as his troops are being engulfed by the water, notice in the background that there are two boulders floating in the water, not being pushed, but floating lightly.
Revealing mistake: A couple cross the road to enter Victoria Coach Station, London. There is the noise of a coach braking hard and they throw themselves away from a coach just inside the entrance, which obviously was not moving at the time. They walk into the station and talk to an inspector, while the same coach is driven out of the entrance past where it is supposedly parked.
Revealing mistake: In the scene right after they leave Scar's wigwam, when Ethan and Martin are speaking to each other around their camp you are able to see a small brown dot right above the sandy hills. This dot is the character Debbie's head while she is waiting for her cue before she runs in to the scene.
Revealing mistake: During the interrogation after the Albert Hall assassination attempt, the telephone used is an obvious Western Electric American-made phone instead of a British-manufactured telephone, betraying the fact that the interiors for the movie were shot in Hollywood.
Revealing mistake: When the German cruiser Graf Spee is seen leaving Montevideo harbour for the last time it is flying the American Stars and Stripes flag from the aft observation platform tower.
Revealing mistake: When Jordan and Jett go into the liquor storage room for Jordan to teach Jett a lesson for beating up Jordie, Jordan instead throws a large wine basket at the shelves of wine/alcohol. The shelves start to fall before the basket even hits them. (02:44:55)
Revealing mistake: As the alien's speak to Carol, Dr. Marvin and the others inside their spaceship, they use the exact same footage again of them looking at the video screen as they leave earth even though one minute of movie time has elapsed. (00:39:25)
Revealing mistake: Toward the end of the film, when Claire Anderson enters the cave where the monster is waiting, she passes a distinctive rock formation. In a later scene, where she is going further into the cave, she again passes the same rock formation.
Revealing mistake: When the monsters are 'flying', the wires are painfully visible.
Revealing mistake: When Frankie punches Barakov, pushing him through the window, not only can you see the wires lifting him, but it is obvious that the inside of the building is a studio set. The wall above the window gets torn - the wall is obviously made of paper and the scenery outside is a painted backdrop. But when the shot changes to outside the building only the window is broken and the wall is intact.
