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.
Continuity mistake: The Packard convertible stolen at the beginning can be seen with and without a rear window during the chase scene.
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.
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.
Factual error: Shortly after the scene where Robin Hood stops the pie cart there is a long shot and in the distance a car is driving from left to right. (01:00:00)
Continuity mistake: Terry Thomas' name appears in the credits inside the green disc of the traffic lights. However, in this close-up the feet of the poor worker are absent. (00:04:50)
