Revealing mistake: Near the end of the movie, when Maverick's plane is about to be launched, there is a quick closeup of an F14's nose gear, which is quite obviously not hooked up to a catapult or anything else.
Revealing mistake: In the opening scene the camera pulls back from a bedside locker to an over the shoulder shot of Kathleen Turner doing her make up in the mirror. Close inspection shows that the shoulder in the foreground is actually that of a double who doesn't quite match Turner's movements.
Revealing mistake: The "blower" on the yellow Firebird never runs. NO wonder he couldn't beat the Wraith. (00:44:10)
Revealing mistake: When Terry dismounts the bus, people on the street look over at the camera. (00:03:20)
Revealing mistake: When Duckie is showing off on his bike, you can see its not Duckie but his stunt double.
Revealing mistake: When Egg Shen helps the others escape by using a crossbow-and-winch device, he fires the bolt into a stone. When the bolt digs in, the stone shudders slightly (since its made of wood or plastic, and no fixed part of the floor).
Revealing mistake: When Daniel and Kumiko first see the storm coming near the end of the film, the wind outside is blowing the trees sideways. They open the door to run out and the camera shows what is outside. The trees there are not moving.
Revealing mistake: When Overlord moves the chairs and tables to block the door, the strings used to move them are visible.
Revealing mistake: When Eddy's mother is lying dead on the bed, she is breathing.
Revealing mistake: When Norman drives Dukes car into the pond, it's obvious no one is in it.
Revealing mistake: A farcical comedy movie does not need to have the most realistic action, but when the protagonists' Volkswagen Thing gets shot down by Turnip's double barrel, the engine 'explodes' with real flames and all, but no bullet holes at all in the metal. It's like it died from being scared. Fun part is, later the detective shows up at Spence's house and mentions exactly bullet holes. (00:28:25)
