Factual error: When Steve gets attacked by the bad guys and Wonder Woman shows up, the lady in the car pulls out a camera and films the event. She sits still, the car isn't moving, and she does all the filming from the same position. However when she watches the playback, the film shows footage from multiple angles and varying distances, which is impossible because she and the camera were in the same spot the whole time.
Visible crew/equipment: While the jet is flying over the Bermuda Triangle the steward releases the gas into the air, and when Steve rushes toward him in the wideshot we can see a crewmember wearing jeans and a blue shirt, at the right side of the screen.Super Grover
Revealing mistake: After the steward releases the gas on the jet everyone passes out, and in the second exterior shot of the jet as it rocks from side to side, we can see the circular frame of the window from which the jet was being filmed, at the bottom right corner of the screen (this shot is flipped).Super Grover
Revealing mistake: During the scenes on the jet with Steve and the others, before landing on Paradise Island and when the Amazon women are aboard, the end of the cabin and cockpit sets can be seen at either the right or left side of the screen in some shots. (Widescreen version).Super Grover
