Other mistake: Max says that Michael is the "Man of the house" and won't come in until he's invited, which Michael sarcastically does, except Michael isn't the man of the house - its actually his grandfather who owns it.
Other mistake: When Westley and Buttercup are in the fire swamp and Buttercup is burned for the first time look carefully at the fire spurt, it's several feet away from Buttercup and is clearly too far away to have burned her.
Other mistake: When Bogomil gets shot two bullets are fired, one by the drive-by shooter and one by Karla, yet there are three distinct bullet holes and a forth large hole in the rear windshield of Bogomil's car. Two holes are completely unaccounted for. (None of the windshield holes are tree reflections.)
Other mistake: Dan and Alex go to what looks to be Alex's apartment after meeting at the office and going for a drink. After romping around in bed, they go dancing, and on the way back through the meat-packing district, she leads him to the door of her apartment and tells him she lives upstairs and he says something like, "this is your building?" It seems odd as they were just up there having sex.
Other mistake: After the one bad guy crashes into the giant vat of toxic waste, hardly any of the liquid from the container spills out for the first two shots. Then a few cuts later, almost all of it pours from the back of the truck. Judging by the size of the hole it left, more liquid should have been coming out around the truck, not just through it. (01:29:00)
Other mistake: In the scene where Chris & Bill are about to bug Maria's phone, she is talking to her mom on the phone & Chris is on the telephone pole listening in. You can hear her talking but not her mom.
Other mistake: When Taryn turns into a punk and walks down the alley way, you can clearly see Freddy's back along the bottom of the camera shot as if he is trying to pass the camera for the next shot. This happens as Taryn looks down the alley. However, if that was meant to happen, wouldn't she have seen Freddy, and not have been so scared when he approached her from behind?
Other mistake: When everyone in the audience and everybody at the betting board see the original unedited version of what really happened at Bakersfield, it shows a soldier hitting Ben with the butt of his weapon from Ben's point of view, which is an impossible camera angle. And as it's the original unedited footage, it won't be something they faked.
Other mistake: When James is on the top of the jeep, there is a brief shot of it from behind as they go past an armed soldier. Watch carefully, the jeep goes over a few bumps and Bond on top seems to jump all over the place in a very unnatural way. This is because the footage has been sped up to make the Jeep appear to be going faster.
Other mistake: When Nitti (Billy Drago) kills Oscar in the elevator, not only is there not nearly enough time for him to write "Touchables" on the wall, but the writing looks like it was done with the aid of a ruler. If he had actually written it in the minute it took the elevator to reach the bottom floor, it would be smeared all over the place. (01:06:50)
Other mistake: When Evil Ed picks up Jake and throws him headfirst into the lightbulb, watch the speed that he hits it and then falls away from it; he moves far to slowly.
Other mistake: Near the end of the movie, in the mansion overlooking the water, James Woods is eliminating the bodyguards. As he shoots the one at the bathroom sink, blood sprays all over the mirror, but the bullet never breaks the glass.
Other mistake: When the Predator sees Billy on the log bridge, there is a cold blotch in the middle of Billy's chest. He's not wearing anything that would make such a hole in his heat signature - it should be the same color as the rest of his torso. It doesn't even match up with the cut he made across his chest; the cut starts much higher than the blotch and the blotch is irregularly shaped, not indicating the smooth line of a cut. (01:15:20)
Suggested correction: The cold area is the blood running from his wound. It is cooling down on contract with the air.
Other mistake: When the sniper fires her rifle at Joker after his rifle jams, she fires at him and strangely no shell casings are ejected. A few bursts later and her rifle does eject shell casings.
Other mistake: Towards the end, when Riggs runs up to Murtaugh just after the car explodes, Riggs is carrying a large machine gun in his right hand. He runs up to the police barricade, but the police officer won't let him by until he shows him his ID. The police officer completely ignored the fact that Riggs was holding a large gun and could have been a criminal who wanted to use it.
Other mistake: When Christopher is in the bathroom stupidly "dabbing" Cathy's back as she's taking a bath there is a glass block window behind them. The window makes no sense. It doesn't match the era or architecture of the bathroom or the home, first of all, but probably more importantly - what's behind it? Where is the light coming from? It's just this random, standing glass block window with an equally-random light source. (00:34:53 - 00:56:49)
Other mistake: When the skater is run over he's covered in blood before the car hits him.
Other mistake: When at sea and during the crew member foc'sle rescue, the ship's crew, including Kevin Costner, are wearing ship ball caps reflecting USS Billings (BB 1369) and the BB represents "Battleship." However they are actually on a Guided Missile Destroyer "DDG 21", the USS Cochrane, as indicated by the hull number 21. (00:15:00 - 00:17:00)
Other mistake: When Eddie Sanger is saving Kathleen Riley from "Michael", he gets slashed in the chest, through his leather jacket and sweater. When they meet up the next day, he is wearing the same leather jacket. Although the front is not shown, it is the same type and colour and obviously same jacket. He doesn't seem to be the type who would wear a slashed and likely bloody leather jacket.
Suggested correction: He gets cut through the sweater only. The jacket was unzipped and does not get damaged, therefore the fact that he is wearing it a few days later is a reasonable decision.
Other mistake: When the man falls out of the high-rise window and lands on the car roof, it never shows him falling through a carport roof. But in subsequent scenes, it shows the car under a hotel-like entrance roof which obviously would have a roof based on the outer pillars. (00:49:00 - 00:51:00)
