Continuity mistake: During the final shootout, when Ritchie comes down the stairs, there is one too few bullets fired for the hits on the walls.
Continuity mistake: Sailor Ripley and Bobby Peru are robbing the Feed Store in Texas. Bobby says "Say cheese" shooting one of the two men. We can see that his right hand is blown off. Cut to a shot of the two men searching for the hand and the victim has a bloody left stump. Then the store dog runs out with a right hand in its mouth.
Factual error: This film is set in Casper Wyoming, yet at the end, as they are pulling away, a visible sign for Interstate 80 can be seen. Interstate 80 doesn't go through Casper.
Continuity mistake: While Reverend Bacon is accusing District Attorney Abe Weiss, the TV remote control that Weiss is using switches hands between shots.
Continuity mistake: After Cody leaves prison and gets in the car with his friends, we see him letting Angel into the back seat, then just two seconds later, when the camera switches to the view of the prison, we can hear the engine started. He couldn't wait for Angel to enter, then enter himself and start the car in two seconds.
Continuity mistake: Lisa drives Sam to the hospital and is met by Dr. Marsh. Dr. Marsh puts on a protective eye mask, before administering a syringe of luminous substance into Sam's arm to stop him projecting fire, but the next scene shows him not wearing the mask then it's back when disposing of the syringe.
Continuity mistake: Fritz stops at the window to Uncle Drosselmeier’s work shop and wipes away the frost to peek. In this first shot, he is on the 3rd window pane from the left. But a couple shots later when Uncle Drosselmeier pops his head out to say hi, Fritz is suddenly only 2 window panes over. (00:02:25)
Continuity mistake: When Joey meets the girl at the disco, when he lights her cigarette, she doesn't have her drink in her hand. Her right hand stays raised, with the cigarette, the whole time; but then one shot later, she's holding her drink and cigarette.
Revealing mistake: When young Norman Bates is spying through the peephole on his mother, who has brought home a man to the motel, we see him in the shower. Although the curtain is translucent, we can see he is wearing a black speedo.
Continuity mistake: During the final battle between Boone and Decker, at one point, they are wrestling on a wooden bridge, and the board beneath Boone's head breaks in half and falls into the cavern below. (It is even highlighted in a very dramatic shot looking downwards over the whole cavern as it falls) Yet, a few shots later, the board has suddenly re-appeared beneath his head, unbroken.
Continuity mistake: When Dr. Jekyll sits down to try his formula for the first time, he removes his ring from the ring finger of his right hand and puts it on the table next to him. After drinking the formula, as his transformation into Hyde starts, his ring is back on his ring finger.
Factual error: When Bill Cosby (as a ghost) goes to the doctor and the doctor checks his heart (which is not beating), Bill Cosby then presses play on a tape recording of a sound of a beating heart. The doctor hears this through the stethoscope, even though the tape recorder is behind Bill's back, which is not possible.
Continuity mistake: The leather straps on Charley's legs on her bed keep loosening up between shots.
Continuity mistake: At the end of the show Damon throws his mic to the floor, and it cuts to a close-up of the mic breaking apart in to several pieces. In the next wide shot the mic is lying intact on the floor. (00:55:45)
Revealing mistake: Obviously not Jane Seymour sitting on the bed topless as her back suddenly looks tanned.
Deliberate mistake: After Ryan and Michelle finish changing the flat tire and are surprised by Leatherface, he chases Ryan around the back of the car and smashes the windshield. At the moment the camera is in the backseat shooting out, we see the chainsaw with the chain popped off and hanging. My best guess is that it was done intentionally (for safety reasons) because the saw was close to Ryan. The crew must've been too lazy to completely remove the chain and just popped it off the track instead. (00:25:25)
Continuity mistake: A helicopter drops two harnesses down to Chuck Norris (Major McCoy) who is awaiting with an unconscious bad guy, and tethers the villain to the ropes dropped by the hovering copter. The black harness ropes are shown dangling from the chopper throughout. When McCoy radios to "pull us up" with the villain in view, the once visible ropes are nowhere to be seen. (01:41:40 - 01:42:05)
