Cobra

Revealing mistake: As the thug shoots up the store, he hits a grocery cart. As it flies up, the pole used in the pneumatic device to launch it is visible.

Movie Nut

Revealing mistake: During the big car chase (in the 1950 Mercury Monterrey), Cobretti throws the toggle switch for a nitrous boost, and the speedometer immediately leaps to well over 100 mph. However, all the exterior shots show that the cars are barely going 35 or 40 mph, in traffic.

Suggested correction: He triggers the nitro when he's well behind the other car, in a wide open area, with no traffic around. His car is from behind, accelerating into the distance. The shot changes to the speedometer. Then the shot changes again, with him having caught the other car, now both going slower in a different area. This area has different scenery, the road markings are different, and it has traffic. They've simply cut the "catching them up" stage and cut back to when there's action.

Revealing mistake: As the bad guys' Ford pickup flips end over end, the device making it flip is briefly visible. Also, the "bad guys" still in the truck turn out to be dummies.

Continuity mistake: In the sedan/pickup chase, both of Cobra's headlights are shot out at the start with pinpoint accuracy. A minute later as the cars race down the freeway, the holes where Cobra's headlights used to be are filled with black plastic discs.
