Revealing mistake: When Rosemary is carrying Hal out of the front door if you look closely at his shirt you can see it moving around from the wires that are keeping him suspended. (01:40:00)
Revealing mistake: In the first cathedral, the Bishop raises his hand before he extends it to Jocelyn and we see the underside of his ring. It is obvious that his ring is a costume ring because it's not closed in the back. This is confirmed on the DVD commentary. (00:23:35)
Revealing mistake: When Jessica and Helen are arguing outside the dress shop, there are 2 girls crossing the street in the background who blatantly stop to watch the scene.
Revealing mistake: This film was shot in Page Arizona with is pretty far north in the "high country". When they first drive up to the meteor side, there is Saguaro cactus that are only a couple of feet high with huge arms and a neon greenish color. These only grow on the desert floor in Arizona and they certainly are not neon colored. Additionally, the arms don't start appearing until they are much taller as they grow them to balance themselves since they have a very shallow root system.
Revealing mistake: In the end at the airport, when Ricky walks up to the line to give his part of the story, you can clearly see a light reflecting off the black cap on Ricky's tooth, to make it look like he has lost one. (01:14:40)
Revealing mistake: Towards the middle of the movie Fats has a motorbike accident and is seen riding into a huge rock. When the stuntman actually hits the rock and goes ballistic there are huge piles of straw right next to the rock that hadn't been there before. In the course of the event the stone gets shifted by about a metre, thus revealing itself as a prop. (00:45:40)
Revealing mistake: When Jack and Marty drive the skinny lady to her inbred folks Jack follows one of them into his house. He has a terrarium where a snake is just swallowing a screaming but otherwise lifeless rat. (00:50:15)
Suggested correction: The rat's last dying gasp? Morticians will also tell you that if you compress a corpse's chest, the deceased will make moaning noises as air from the lungs is forced out and past the vocal chords. Why couldn't the same process happen with a rat?
Revealing mistake: When Ricky and Bobby knock the fishbowl over while fighting, you can see it separate into two clean halves before it even falls. (00:40:05)
Revealing mistake: After Steelleg's and Iron Head's song, Steelleg is taken outside for a fight with some thugs.

Revealing mistake: When Kakihara is smoking in the beginning, you can tell the cigarette is not really lit, and that the glow of it was added later using computer graphics. The easiest way to notice this is to notice how no smoke is coming off of the cigarette itself.
Revealing mistake: When the girls do their 'Entrapment' routine jumping through the lasers at the diamond vault, you can see them cut through the beams with their arms, legs, and hair.
Revealing mistake: When Michael is gambling his money away, the first time we see him throw the dice on the craps table, the dice head off camera to the top and upper right corners. When the dice "bounce back" they come from the upper left side of the screen together as if thrown from right off camera.
