Revealing mistake: During the end scooter sequence along the cliff tops, you can clearly make out wheel tracks stretching out ahead of Phil Daniels' bike, yet he hasn't been over that ground yet - these are presumably left-overs from a previous take?
Revealing mistake: When the sheriff's car is flipped upside down, the sign behind the car is upside down too, so you can tell the car isn't really upside down.
Revealing mistake: When Chris Tucker is found dead from an apparent heroin overdose, you can see him still breathing on the chair.
Revealing mistake: When Jack is hanging out of the truck you can see him standing on the hood of the car which Lydia is driving. At some points we get camera view from the back seat of the car. In some angles the mirror inside the car disappear. This is to prevent us from seeing the camera. (01:04:15)
Revealing mistake: When Costello's men drive off, after throwing Queenan off the top of the building, the state troopers are firing at the van. One back window is shot out, then in the next shot of the van the other window is shot out and then the same one is shot again so the one window is shot out twice in the same scene.
Revealing mistake: When the Joker is having the party with all the balloons, Vicky Vale tries to escape from the gas by getting into a car. If you look at the back window while she is driving off, the window is rolled down, which would have led to her death, not to mention motor vehicles are not air tight to begin with.
Revealing mistake: As Terry and Martine approach Le Sac shop, you can see reflections in the window of that shop of trees. This gives away the fact this was a custom built set (as shown in the extras) and not the real location in London. (00:20:05)
Revealing mistake: When the little boy steals the wig from the dead Rug Daniels' head Rug blinks and twitches his lip. (00:16:45)
Revealing mistake: In a scene where Frog is riding with the Bandit, she's resting her head on the center gearshift console. Although they're supposed to be cruising down the road, the automatic transmission shifter is in neutral.
Revealing mistake: In the final scene as Doc tell Billy good-bye if you look up to the top right hand corner of the screen you can clearly see a jet trail in the blue sky. Certainly not possible in those days. (01:42:20)
Revealing mistake: When the Hummer is flying through the air, you can see that most of the underside of the vehicle is missing, the engine, transmission, driveline, fuel tanks, all gone.
Revealing mistake: At the air field there is a scene when Cyrus is loading his gun. If you look closely at the clip you will see that it is hollow. You can see right through it. (01:22:05)
Revealing mistake: After the first race, when Tej walks over to Brian with a bunch of people, there is a girl in a orange and black top, and as she walks towards Brian, she is looking directly at the place where the camera is supposed to be and backs away, so the camera can pull in for the shot. (00:13:10)
Revealing mistake: Any time that Charlie is kicked by the kangaroo, they show him falling back onto the ground. But, if you look closely, they just used the same shot over and over. The exact same two lines in the dirt are to his left by his head each time.
Revealing mistake: When the police car crashes through the grating that was dropped down in front of it at the end of the tunnel, the occupants are dummies - they just bounce about in the same upright position whilst the car drives into the river.
Revealing mistake: When Memphis delivers Elanore to Calitri, he gets punched and falls to the ground. At his feet you see orange tape as stage markings. (01:38:15)
Revealing mistake: There is one scene where Alicia Silverstone is being taken away, and in the window, in the background, you can see a metro train with the letters on the side stating BC Transit and a picture of the British Columbia flag. Yet, the whole movie supposedly takes place in Washington state.
Revealing mistake: When Ripley is leaving New York, there is the shot of the ship sailing out of the harbour. Check out the water - one layer has been 'cloned' on top of another.
Revealing mistake: Near the end of the scene, when Bruce and Fox are in the tumbler Fox says "We never could get the damn bridge to work, but this baby works just fine" then Bruce turns the wheel to the left but the tumbler turns right. (00:57:45)
Revealing mistake: After they kidnap Neil, they are driving to stop the wedding, as they are driving down the road, you can see out the front window that the truck pulls up to a stop light. They cut to Neil and the truck is still moving, then they cut back to the group and they road is clear. Traffic lights don't cycle that fast. (01:20:30)
