Revealing mistake: In Houston, when a man is thrown through a truck, notice the ground he falls on: The sand is leveled higher than the rest of the road around, obviously to hide a landing mat. Furthermore, after the fall the man turns around and he's got a bulgy square on the back to help for a safe stunt.Sacha
Continuity mistake: When Ursa says to the Cosmonaut "What kind of creature are you?" her whole body is facing forward. He responds "Just a man" and in the next shot of her, her body has turned left. Then when she goes to grab his patch her body is facing forward again.
Other mistake: The cab that slammed into Clark earlier in the film is seen coming around a corner during the confrontation. The amount of damage inflicted from running into the equivalent of a thick concrete pole should have rendered it inoperable, as the radiator was pushed back into the engine. Even if repaired, the front would have been repaired as well.Movie Nut
