Revealing mistake: In the scenes inside the space capsule, as Roy goes through the sequence, the wires holding him up in the floating sequences, and the crackers when trying to eat, are visible.
Continuity mistake: The Packard convertible stolen at the beginning can be seen with and without a rear window during the chase scene.
Continuity mistake: At the beginning, the scientists are told they are being sent to study the strange fact that seven meteors landed near each other in a V formation. The government agent even traces a V on the board with his finger. When they get to the field, panoramic shots show that there are nine meteors, and they are in a 3 by 3 grid, not a V.
Factual error: When Jeremy and Jack climb the beanstalk and arrive on the clouds, it starts to rain. Where is the rain coming from?
Continuity mistake: Pauline is driving in the one-way street, of course the wrong way. There are several continuity errors between cuts; for instance when you see the 'boy' in the back seat laughing hysterically behind her, in the background you can see the red pick-up she nearly has a frontal with in the next shot. (00:05:00)
Other mistake: When the convoy of getaway vehicles arrive at the scrap yard, after dropping the loot of at the airfield, two of the jeep type vehicles have the same registration number - 247EJF.
Factual error: When Miriam is pacing, waiting for Tony to come home, she is listening to Tony singing "Come Live with Me" on a reel-to-reel tape recorder, but the recorder has no speakers, either built-in or separate.
