Other mistake: When the two Americans are walking on the moors, their shadows are always in front of them, despite them having changed direction numerous times. Additionally, with the moon always being behind them, how are their faces being lit?
Other mistake: Watch the scene where the drunk Ben Tramer (wearing a similar Michael Myers mask) was hit by the speeding cop car and then pinned against the parked van before burning. Even taking out the equation of accidentally hitting Ben Tramer, what was the cop car doing speeding at that rate of speed, head on towards a parked van on a side street? Remember, we only hear screeching brakes after the car hits Tramer, and we never see the cop car swerve or any of that to miss hitting the van. Seems that even if Tramer hadn't been there, the cop car was sure to barge head on right into that van.
Other mistake: When Joan is cutting up her rose garden, she is ranting and raving about how mad she is at Mayer, and how they're calling her box office poison. But if you look closely at her lips, they aren't moving.
Other mistake: Right at the part where Crazy Ralph is looking in on Paul and Ginny. Ralph hears a breaking of a stick behind him. You can see Jason put the barbed wire up and over the tree. How is that possible? He would have to whip it around the tree, not over it. (00:30:20)
Other mistake: When attacking the convoy, the crew rushes forward during the crash dive. Just after a crew member jumps through the hatch after the bow crew compartment, you see someone standing still a second before getting pushed in the view of the camera. (01:31:15)
Other mistake: Dennis Quaid is supposed to be frozen in a wall of ice but if you watch closely, and very quickly, you can see him blink his eyes.
Other mistake: Towards the beginning of the film JJ (Burt Reynolds) lands his plane in a town to get more beer. You can clearly see the a large crowd of spectators in the background standing behind the wooden barriers which the police had set up for the filming.
Other mistake: When Arthur is in the bath tub, Hobson brings him a martini on a tray. Arthur grabs the glass. It shoots over to Hobson then back to Arthur and he picks up the glass again without even putting it down.
Other mistake: Toward the end of the film, Cora and Frank put the top up on their roadster, then drive off without latching the top.
Other mistake: There's no way Harry could've smashed the cigarette vending machine at the gas station without somebody inside seeing him.
Other mistake: In the scene where Mel Gibson is playing AFL with his fellow soldiers during training in Cairo, we see him wearing a digital wrist watch when he whistles and raises his arm. (00:49:30)
Other mistake: Towards the end when Janet, Brad, Oliver and Betty are singing "We're going to do it anyhow," as they are dancing down the aisle, Betty very visibly trips and grabs Oliver to stop from falling over.
Other mistake: For corpses which have spent around a decade lying in water, the zombies' hair and uniforms are surprisingly well-groomed.
Other mistake: When Perseus wakes up in the stadium and he is talking to the old man, you can see a flesh coloured pair of shorts under his tunic.
Other mistake: When Max is making his escape from the compound in the Interceptor, he turns on the blower to speed through the bad guys' camp. Here you can see everyone running at fast-forward speed.
Other mistake: When Arthur and all his knights assemble on hilltop at night and Merlin tells them all not to forget where the Round Table started, you can see the crew's spotlights reflected on the back of some of the knights' armour.
Other mistake: Towards the end, Capt Williams blows up some buildings (or caravans) to try and stop Hart from continuing, and flies off. When Hart later stops, the same buildings are blowing up again. One could argue that it's being seen from a different perspective, but in the wide shot after Williams flies off, the car cannot be seen.
Other mistake: In the casino scene they're playing Baccarat. Bunky reveals a natural 8 (5 and 3). When Bond's hand is revealed, the croupier announces 9 for the win: "et neuf la banque" ("and 9 for the bank"). Only, Bond has revealed a Queen and a 5 (a natural 5).
Other mistake: At the end after the barn fire, Marcia is at a tavern, ordering a rare steak. While it is believable that she escaped the barn fire, it is unbelievable that she is in the tavern wearing the same dress and necklace she wore prior to her transformation in the barn. All of her attire would have been rended in the transformation and lost in the fire. Unless her wardrobe consists of duplicates of the same clothing.
Other mistake: In the private conversation scene with Bill Murray and "Sarge" in the latrine at basic (Sarge's office) the toilet bowl in the back left corner is installed backwards. (00:43:03 - 00:45:10)
