Revealing mistake: When Herod shoots Rusty in the back before the final gunfight, a car can be seen driving down the road in the background.
Revealing mistake: At the cemetery, a reporter nudges a headstone and it moves, revealing it is fake.
Revealing mistake: When Vida, Noxema and Chi Chi decide on the convertible they pull forward a few feet. The catch their "reflection" in a mirror of some sort. When viewed with great scrutiny we see that in fact this is not a mirror reflecting their image but a camera shot of them that has been reversed. The special effects guy placed the lights around the clip to make it look like a mirror. When seen numerous times we can see the image shake a bit and that the image moves ever so slightly within the light bulb frame. (00:17:50)
Revealing mistake: When the eye doctor becomes hypnotized to put the wrong drops in her own eyes, if you watch the bottle nothing ever comes out of it that could cause her to scream.
Revealing mistake: After the XO orders all stop, we see a close-up of the ship's yoke being pulled back. The next wide shot shows the interior as the bow of the sub is rising, and just before this shot ends, note the console that the man with headphones is working at. A pair of crewmembers cross paths in the foreground, then the entire console wobbles, proving it isn't attached to the floor at all. (01:09:00)
Revealing mistake: When the tube is being inserted into Crazy K's nose, an imperfection in the tube is visible near the orderly's fingers. It doesn't move, despite the orderly "inserting" the tube.
Revealing mistake: Obvious stunt double for Susan Lucci in the skinny dipping pool scene. The stunt double's hair is longer and straight while Susan's goes past her shoulders only some, has bangs and is slightly curled.
Revealing mistake: When Rimbaud dies, as the nurse covers him with the white cloth, he blinks for a fraction of a second.
Revealing mistake: After stealing the battery out of Durant's weapon near the end, as Westlake says "Batteries not included", you can see the actor's undamaged lips under the fake burn prosthetics on his face and mouth. (Look underneath the exposed teeth where his lips supposedly were burned off.).
Revealing mistake: When the hitched car driver makes a left turn, check Nomi's hair and you'll notice that she's been replaced by a stand-in.
Revealing mistake: When Kinjo is fighting Saito, he throws away his sword and fights Saito with his bare hands. During the duel, he first slams Saitos arm over his knee, then elbows him in the side of the head. But look at Saito's head; he reacts to the elbow LONG before it connects.
Revealing mistake: When the family heads to Sears and are first playing with the cameras, Jan's show that her movements in her camera are slightly different and not the lag factor of the image being displayed on the TV.
Revealing mistake: When McCord climbs to the top of the arena he fights with a guy patrolling the rooftop. He then kicks the guy over the edge, but the way the guy falls back shouldn't have sent him sliding down the roof.
Suggested correction: He pushes the guy with enough momentum to slide down the roof.
Revealing mistake: When Katie is making Sharkey levitate as part of her circus act, you can see the shadow of some rigging connecting him to a nearby pillar. (01:43:50)
Revealing mistake: At the start of the film, Sergeant Gunn and another member of his tank crew take shelter in a shell hole as they are returning with fuel and spare parts. Watch the supposedly dead soldier hanging over the edge as they leap into it - he visibly reacts and moves his head.

Revealing mistake: The mix of two shots is obvious such as the photographer inside the centerfold's top.
Revealing mistake: The width of the telephone pole behind Ebbie is about two-thirds the span of her shoulders but is just as wide when the background is blurred. (00:22:10 - 00:23:18)
Revealing mistake: When Annie's boyfriend is killed, she runs over to Candyman and scratches his face open and bees pour out. You can easily see the head is a prop.
