Revealing mistake: In the catacombs of the library, Indy and Elsa are waist deep in petroleum. Indy has a torch, and if you look carefully, you will see burning pieces of the torch fall and hit the petroleum. Wouldn't this start a fire as Kazim later on sets the cavern alight with a single match? (00:34:05)
Revealing mistake: When Doc and Marty arrive in 2015 when the car is landing in the alley you can see the mechanism that is lowering the car. Just as the scene switches from the front of the car (right after the headlights go out) to the back of the car, look between the car and the building at the same level as the back bumper. There is something that is moving down with the car. Also, the vents in the back of the DeLorean are different. (00:06:12)JamesP
Revealing mistake: In the scene after the battle of Agincort, where Henry and his retainers are walking meditatively among the heaps of the fallen, if you look carefully, you will see one of the fallen with his head raised watching the procession. He then realizes that he is on camera and puts his head back down. It's near the edge of the screen so may occasionally be cropped.
Revealing mistake: When Sybok lifts Kirk off the ground in the shuttle bay, wires are visible holding up Kirk by his legs.
Revealing mistake: After Art and Ray successfully blow up the Klopek's house, Ray emerges from the ruins and the porch collapses behind him. It can be seen that the porch supports are dragged backwards towards the house to allow the porch to collapse behind Ray.
Revealing mistake: When Lupe Lamore puts Sanchez's iguana down on the table near the end of the movie, you can see the iguana bounce slightly. Also, it isn't breathing.
Revealing mistake: When Kurt is loading his brother into the van on the stretcher after the fight when he has just been paralyzed his feet are sticking out, but when the door is being shut he pulls them in.
Revealing mistake: When Swayze gets into a fight in the bar office with an employee who was recently fired, he ends up going through a window with another thug during the fight. Watch carefully as they go through the window. The falling man has a hair style significantly different from Swayze; it's his stunt double. It's more obvious as he hits the table in the continued shot. (00:38:25)
Revealing mistake: When Dave and Walley are running with a car, Walley says that he heard some shots. Dave replies that he didn't hear anything, but as you know Dave is deaf, and he reads Walley's lips each time he speaks. In this scene, he wasn't looking at him, but answered. (00:47:45)
Revealing mistake: After the water tentacle sequence, Coffee brings Schoenick back to their bunks to get the submachine gun, so they can take over the rig. The bag containing the gun is stashed behind some pipes up by the ceiling. Watch when he reaches behind the pipes to grab the bag--the pipes move at least six inches. (01:31:57)rbryant73
Revealing mistake: After Dooley and Jerry Lee were shot at and the window was blown out in Dooley's Mustang, they give chase to the Mercedes, look carefully at the "dog". In two shots in the chase sequence, you can see it is a fake dog and looks very much like the fake dog in the bar scene lunge. (00:56:30)
Revealing mistake: When Briar is reloading cartridges in the flop house, he's removing powder from an already spent shotgun shell. The primer is indented.
