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: 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: 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: 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: The alien is starting to mess with all sorts of mechanical and electronic devices. One of the first ill-effects shown is a large industrial cable reel that is dangling in midair when the mechanical arm lifting it is paralyzed. Problem is, you can see the operator has his hand on the controls and is stopping the crane himself using the lever, nothing alien about that. (00:14:50)
Revealing mistake: When the monsters are 'flying', the wires are painfully visible.
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)
