Continuity mistake: After the Stormtrooper tells Darth Vader the Death Star plans are not in the main computer, when Vader lifts the Rebel off his feet by his throat as the Rebel tells him they intercepted no transmissions, take note of the leg plates on the Stormtrooper to Vader's right. In the wide shot, the Stormtrooper's left leg armor does not have the knee protector plate (it looks as if it's at his right knee because the extra switched them), but in the next closeup the knee plate appears at his left knee, as it should be. The trooper also appears to go from right handed to left handed weapon carry. (00:05:40)
Continuity mistake: After the Bandit jumps the bridge Sheriff Justice rear-ends the cop car in front of him, smashing the hood of his car. In the next scene Sheriff Justice's hood is fine.
Continuity mistake: In the scene where Stromberg is thanking Dr. Bechman and Professor Marcovitz, he has a towel in his hand. When the camera changes to another angle that shows the back of his chair, his hands are totally empty and resting on an arm of the chair. Then it changes back to the original camera angle, and he now has a towel in his hands again.
Continuity mistake: Near the end, while Kabakov is atop the blimp, he finally attaches the cable hook to the blimp. Just as he wraps the canvas strap around the hook, Kabakov's white shirt is neatly tucked into his pants, whereas in the previous and following shots, his white shirt is fluttering in the wind and we can see his abdomen and back.
