Revealing mistake: During the "Anything Goes" dance number, the shot of the dancers doing the 'splits' is simply ran in reverse to produce the illusion that they're rising up from the stage floor.

Revealing mistake: Near the end of the movie just before Van Helsing drives a stake through Dracula's heart, Dracula leaps out of his coffin and impales Van Helsing with the stake. It's very clear that the person getting impaled is a stuntman with an 'Olivier' mask.

Revealing mistake: When Leon and Deckard are fighting in the street, Leon swings at Deckard and puts a hole through a steel vessel where steam blasts out. It's clear that the spot where Leon hits has been cut out and is visible before he hits it. (01:02:15)

Nicki

Revealing mistake: When Spock's shuttle is lining up to dock with the Enterprise, look below the shuttle and you can see the hydraulic mechanism used to maneuver it.

Nicki

Revealing mistake: When Comicus et al are running from the Roman soldiers, Miriam pulls Comicus through a secret marble door. When it closes, you can see the glue residue revealing that it's Formica.

Nicki

Revealing mistake: When Godell is trying to get away from the company's goons, he races to the nuclear plant gate where he'd be safe. As he pulls up to the gate, you can already see the 'donut' skid marks left in the driveway from the goons' car when it turns around. But the car turns around AFTER Godell pulls up to the gate, so the donut must be from a previous take.

Nicki

Revealing mistake: Mel jumps over a step that he senses to be weak. The step he actually jumps onto (and collapses) has been pre-cut in a zig-zag pattern. (01:26:50)

Nicki

Revealing mistake: As a very young Otis Williams listens to The Cadillacs on stage in Detroit, the joint is rockin' with the music, but most of The Cadillacs have no microphones.

Nicki

Revealing mistake: When Quade shoots Dr. Edgemar, Lori yells "Now you've DONE IT.", and the wall explodes, which is plainly made of foam. Many of the pieces of 'wall' tumble lightly across the floor. (01:05:40)

Nicki

Revealing mistake: Right before Quade jumps on the train to get away from Richter, he uses a gun to break one of the train windows. His gun barely (if at all) touches the window and it shatters. (00:31:40)

Nicki

Revealing mistake: After Rhett tells Scarlett that he doesn't give a damn, she's just inside the front door and places her hand on leading edge of the door, which moves when she touches it to support herself.

Nicki

Revealing mistake: When the killer satellite rocket reaches orbit, you can see it 'bouncing' up and down as the pieces separate.

Nicki

Revealing mistake: As Harry approaches the Acorn Cafe (which he is about to shoot up), you can see that the two window panes just right of the door are candy glass. This is confirmed when one of the 'heavies' goes flying through them after Harry gives him the .44 Magnum treatment.

Nicki

Revealing mistake: When the neo-nazis burst into Kohler's apartment, they stab him and he slides down with his back against the wall. While Mengele picks up the phone, you can see the 'dead' Kohler blink in the background.

Nicki

Revealing mistake: In the alley, The Mask tells one of the street thugs that he's going to pull his underwear over his head. Here you can see that The Mask's rubber 'skin' is peeling up on the back of his neck.
