Continuity mistake: When Bond escapes from the Willard Whyte facility in the desert in the moon buggy, a car that is chasing him goes over a ridge and turns on its side, as the buggy speeds by. A wheel rolls back into the shot, all on its own. It doesn't belong to the car or the three-wheelers also chasing, but looks like it belongs to the buggy, which has its full complement of wheels all through the scene.
Continuity mistake: In at least one scene, traffic lights are shown flashing. Where's the power coming from?
Continuity mistake: On Day 2, when the two officers go into the town's doctor's office, they leave the van with the driver's door way open, beyond 90 degrees, almost 180. The door didn't move to indicate it corrected itself as they went in. When they come out, the door is almost closed. And there has been no indication of a wind other than the helicopter, and that is supposed to be 1000 feet up and not even close to the office.
Continuity mistake: When the scientists are using the blocks on Zira, Zira is told to point to the blue blocks. As she points, the blue block is at the front of the pile from the scientist's perspective. In the next shot, the blue block is suddenly in the middle of pile. (00:13:30)
Continuity mistake: When Willard goes to confront his boss, Al Martin, about killing Socrates earlier that day, we get a good view all around Al Martin's office. There are a few rats on the desk, coffee table and a chair; but there are absolutely no rats climbing the curtains. Al Martin realises Willard is insane and they struggle briefly, whereupon a single rat leaps on Martin's arm and bites him as he screams. In that moment, seven rats suddenly appear climbing high up on the curtains behind Al Martin. The camera makes a one-second cut to Willard for his famous line, "Tear him up!" The camera immediately cuts back to Al Martin, and now all the rats have disappeared from the curtains in the background.
