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 Howard's running from the female bikers, Satan's Sluts, look closely at one and you can tell it's a guy in drag, one wearing a dark blond wig. (00:10:00)
Suggested correction: I was in this part of the movie, everyone in this scene (except for the duck) is female.
Revealing mistake: When Turnip mounts in the car (ending up destroying the passenger door), the car has the rear-view mirror. During the chase though, the mirror is gone, but it's back when they finally block their way in the alley and Turnip whacks his own nuts. (00:26:30 - 00:28:30)
Revealing mistake: When Norman drives Dukes car into the pond, it's obvious no one is in it.
Revealing mistake: When Eddy's mother is lying dead on the bed, she is breathing.
