Continuity mistake: When Vader's shuttle is approaching the Death Star, the crew in the control room of the Death Star are wearing black gloves. One of them then reaches forward to press a button, but in the close-up of his hand pressing the button, the hand is not wearing gloves at all. This can only be seen in the widescreen version.

Visible crew/equipment: When Superman is landing to stop the plough machine, the wires holding him are visible.
Factual error: When we first see Fatima Blush, she is waterskiing. She is doing several stunts, which are only possible with one ski, the most notable being skiing backwards with one foot in the air. However, when she releases the tow rope and skis up the ramp into James Bond's arms, she is on two skis. (00:45:55)
Continuity mistake: When Bond takes off in the plane, we see - in one shot from Bond's view - the Cubans approaching. The background is a flat (English) countryside. In the next clip, we see a close-up of one of the Cubans. behind him are quite large hills/mountains. (00:04:55)
Revealing mistake: When Nicole's bike jumps over the kids lying on the ground there's a ramp beside them disguised as part of the road to allow for the stunt.
