Other mistake: Mister cooks Shug Avery a breakfast of grits, biscuits and ham, and takes it to her room. She throws the breakfast against the wall. The breakfast leaves a bright yellow and bright red stain on the wall. There was nothing on the tray that could have left those colors on the wall. (00:51:10)
Other mistake: When Rocky is in the funhouse looking at himself, he appears to look relatively "normal". But it's very obvious that it's got nothing to do with the mirror, and more to do with the removal of a lot of makeup. For example, Rocky usually has almost no nose, but in the mirror he has Eric Stoltz's very well developed nose.
Continuity mistake: After a long car chase about mid-way through the film, the camera pans over the highway littered with smashed cars and hundreds of cars piled up. In the middle of this, you see a van painted a little like the Partridge Family bus....definately a one of a kind van. Then you see footage of the car which escaped the chase going down an empty side street and passes the same van. No way there are two vans like this one.
Plot hole: When Schaeffer, McFee, and Fergie drive to the Lapp farm to kill John, the car stops on top of a hill. Then it reverses a bit to be out of sight from the farm. But then the formerly careful guys get out and walk down the open road, sporting their guns like in an Italo western. (01:28:30)NancyFelix
Plot hole: When Diana turns up at her director friend's house she finds it crawling with cops as his girlfriend Christie has been murdered and the house is now a crime scene. She explains she lent Christie a coat and is there to pick it up - and a cop helpfully finds it on the floor and hands it to her. Are we to believe that a homicide policeman will hand over an artifact from a murder scene to an unidentified woman without making any attempt to confirm her identity, or even if the coat is even hers!? They don't even ask.
Continuity mistake: When the Antereans go into the sea for about the second time I think, Jack stays on the boat and starts playing about with the machine and makes it go off. When it does he drops a load of sweets or nuts out of the bag he was holding, but when the camera cuts away then cuts back there are no nuts or sweets on the floor.
Continuity mistake: When Kersey goes into the post office and his girl is waiting in the car, Fraker and his goon knock her out and shove the car down the hill. As it goes down there is a view of the back of the car and the reverse lights are on. Then as it is about to hit the other car, the lights are now off.
Continuity mistake: When Leroy is fighting Goliath in the club, the bald headed guy changes between lying face-up and face-down in almost every shot.
Audio problem: When Wendy and Jules are talking in the bathroom, two women walk by and say "Hi Leslie" and "Hi Les, how ya doing?" to Leslie. It is easy to see that their mouths do not move in sync with the words that are heard.
