Deliberate mistake: Has there ever been a more obvious body double than the one used for Angie Dickinson in the shower scene? Not only does the top of every shot stop right at the collarbones, she is much taller than Dickinson, she has a much deeper tan and (of course) her breasts are much, much bigger. In fact that is Victoria Johnson, Penthouse Pet of the Month for August, 1976.
Continuity mistake: When the windows on Nick's truck are smashed, Elizabeth has protective gloves on when she covers her face from the glass, they are then gone when the truck comes to a halt.
Deliberate mistake: At the end fight scene, when they are in the barn one of the men falls crashes through the wall when they get hit, spilling the fight to the outside. Unless the barn's walls were made of cheap plywood, the wall would not have given away so easily. Obviously done for dramatic purposes.
Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Continuity mistake: At a meeting to do with the hospital's dealings, one man, Mr Broadbeck, objects to the Elephant Man being a patient in the hospital - in the beginning he is wearing spectacles, but, a few seconds later, the spectacles are gone.
Continuity mistake: There is a scene in which it is raining quite heavily and Em and Richard are inside the hutch. Richard is playing Pop Goes The Weasel over and over which annoys Em. She stabs him in the foot and he chases her outside. In this scene she is wearing a strapless dress but when he catches her and pins her down on the sand she is wearing a lacey jacket (she didn't have time to change) and there are no clouds or rain. The sand doesn't seem to be very wet either, despite the fact that it was raining heavily a few minutes ago. (00:41:10)
Continuity mistake: The egg timer in the jail is about to run out, but when Dale runs over to it and tries to turn it over, there is more sand in it than before.
Visible crew/equipment: When Harris and the two Irish men have been killed at the end and the car crashes on top of the other the ramp used to make it fly is visible.
Continuity mistake: When McVicar is going crazy he knocks the food off the table along with this yellow cup, however this reappears on the table again.
Continuity mistake: When the lady anthropologist gets out her teacher's car - you can see in the background the traffic lights changing from green, to amber, to red. When it cuts to another view of her - the traffic lights are on green.
Visible crew/equipment: When one of them is using the bathroom - out of the bathroom window and it sprinkles on his neighbor's flowers, watch when the camera view goes up because you can see someone squeezing a rag onto the porch banister to look like his pee.
Revealing mistake: When Tony is having his first fight in the embassy, it is obvious that most of his punches do not connect at all. The people he supposedly hit still react as though being hit, and the sound effects of a fist hitting a jaw are still there, even if Tony misses by several inches.
Revealing mistake: During the scene in which Lou forces himself on Kim in the lunchroom, donning a black ski mask, Kim's brother Alex jumps up to his sister's defense. Just before Alex throws his first punch, Kim screams "Michael," referring to the actor's real name Michael Tough. Kim then correctly screams "Alex," the name of the character he was playing in the film.
Continuity mistake: Skeletons of murdered prisoners are dug up on prison grounds. While Brubaker & the prison doctor examine the bones, it is pouring buckets of rain. They determine the head trustee is responsible. The next scene shows a pickup speeding down a dirt road kicking up clouds of dust in the blazing sunshine. All that water sure did dry up fast.
Factual error: A film about the making of a film. A car is filmed going off a bridge, and the footage is played back repeatedly. Throughout, the car is referred to as a Duesenberg, even though, in nearly every shot, the Mercedes tri-sected circle logo is visible above the radiator.
Continuity mistake: In the restaurant scene where Conrad is sitting opposite Karen, the position of the drink glass in front of Conrad changes as the camera angle moves from Conrad's back facing Karen to Karen's back facing Conrad.
Continuity mistake: When Kate ask if Sam Boga is scared to admit he's made a mistake, Sam Boga is carrying his rifle in his hand. When it cuts Sam Boga has his rifle shouldered. (01:24:00)
Deliberate mistake: The 100-meter 'dash' goes over a longer distance and lasts longer than shown in the movie.
Audio problem: When Benson is dismantling Hector and putting his brain in the container, he says 'What you can't stand, you run from,' but his lips don't match what he says. (00:48:50)
Other mistake: At the end of basic training, Judy's platoon goes to the bulletin board to see what their M.O.S. will be. This is not how the U.S. Army operates, you must pass a qualification test for the M.O.S. that you enlist for before you ever enlist. You know before you ever get to basic training what M.O.S. you will be training for, not on the last day of basic training.
