Other mistake: Murphy lands the helicopter on a railway line so an oncoming train will destroy it completely, and this happens exactly on cue with huge, dramatic explosions and flying debris. Apparently the train driver doesn't think this is important enough to interrupt his busy schedule - he doesn't stop the train. We do not hear brakes being applied - the wheels would make a noise like the sky coming down - and the train doesn't slow down at all - it just keeps on going.
Other mistake: Interior Minister Roger Frey advises Commissioner Lebel that all members of the police, military and other security forces attending the ceremonies on the day the Jackal is expected to strike will be issued with lapel badges at the last moment, in case he is going to try to masquerade as one of them. We see hundreds of such people in the next part of the film, including Lebel himself and the CRS private who allows the heavily disguised Jackal through the barricades around the site of the ceremony DeGaulle is due to attend. Only the CRS private wears a lapel badge. Not one of the other police or military officers in attendance is wearing a lapel badge of any kind. (01:58:15)
Other mistake: Nadia appealing for a lawyer to act on behalf of Mrs Yakamoto in her divorce is pointless. An American lawyer would be of no value to her: her divorce (should she decide to go through with it) would be heard in front of a Japanese court, and they are extremely stingy with women who divorce their husbands. Nadia may not know that, but Mr and Mrs Yakamoto are Japanese nationals - she is wearing traditional dress! The American lawyers would know perfectly well that the divorce would be handled by a Japanese court - the US would have no jurisdiction at all.
Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Other mistake: Throughout the film Mason goes through all sorts of shenanigans - explosions, fire fights, falling off a cliff, almost drowning, this woman really goes through the wringer. It's a bit surprising then, that at the very end of the film when the good guys finally come to the rescue that she looks like she has just finished posing for a shampoo commercial with not a hair out of place.
Other mistake: Ginger is adamant that she will not approve any plan of escape that does not get all the chickens on the farm out and to freedom. The problem is, not one of her plans gets anywhere close, and it is not that they fail to liberate the whole farm - they are never planned that way. We see her trying to escape by herself three times. The mannequin of Mrs Tweedy would (had it worked) have allowed nine chickens to escape, the upturned feed tray just seven. Even the 'crate' appears to hold not more than thirty chickens - and there must be several hundred on the farm, at least.
Other mistake: In the slaughterhouse scene, after Harrigan has injured the Predator with his shotgun and Keyes reappears, the Predator throws its disc, and severs Keyes in half at the waist. We see his legs flop to the ground, and blood pour from above, but his upper half (torso, backpack and weaponry) mysteriously remain hovering out of sight. (According to the director, the MPAA made him cut the footage of the top half of his body hitting the ground because it was too gory, creating this odd error). (01:21:50)
Other mistake: How could Jane not be aware that Tom had only used one camera for the date rape interview, recording his fake tears later? That's the way things are done on television news shows and as an experienced, hard-bitten television producer she could not possibly be unaware of that. The reporter always records his or her reaction shots (called 'noddies') after the interviewee has left. Shooting with two cameras would involve two crews, two lighting rigs, a vision switcher and so on and so on and a straightforward interview simply would not justify such a complex and expensive set up.
Other mistake: There is something drastically wrong with the design of the spherical 'Aries' moon shuttle. Some seats and many fixtures are 'upside down' relative to the up-down orientation of the shuttle itself, and we see loose food trays and equipment about the place as if this is routine. But - the shuttle is designed to land on the moon. What happens then? The moon has gravity, remember? There are going to be quite a few very disgruntled people dangling upside down like spiders, and there will be loose gear (and perhaps a stewardess or two) bouncing about all over the place. It is not a matter of stowing loose gear or lying flat on landing - some parts of the shuttle are upside down relative to others, which is why the stewardess has to do that famous 180 degree upside down walk. Whichever way you look at it the shuttle is going to encounter serious problems when it reaches a gravity well, which will occur whenever the engines are fired up, never mind landing on the moon.
Other mistake: Fireworks use heated metals to produce the various colors seen when they explode - Iron, Nickel, Cryolite, magnesium and copper filings. Flying a jet engine through exploding fireworks would cause serious damage to the engine.
Other mistake: When Nash is put into the car and is being taken away to the hospital, there is a line of people watching him drive away. Two of the spectators are the imaginary roommate and the little girl. They are standing in front of rest of the spectators. As the car is driving away you see a female student look around the imaginary roommate to see the moving car. If the roommate can only be seen by Nash why did she need to look around the roommate to watch the car drive away? (01:08:30)
Other mistake: In all the shots of ET wearing the white sheet the two eye holes are about a foot apart, so he could see out of the holes properly, but when Michael finds the white sheet ET had been wearing he lifts the material and we see that the two eye holes are only about two inches apart, which makes no sense. (It was Gertie's sheet which had eye holes that close together).
Other mistake: The female journalist is called Samantha Coleman through the movie, but appears in the credits as Samantha Copeland.
Other mistake: After the great fire scene there is a raccoon that drags her baby to shore and begins cleaning it. A few seconds later the baby has jumped across to the other side of his father and siblings, but the mother does not stop licking. This error has since been fixed in newer releases.
Other mistake: In the scene where the kids are shooting arrows and the coach gets hit by one, they send a girl to call 911. If you look closely and follow her in the background, after she runs a few yards, she slows down and eventually stops and stands there playing with her hair. Talk about help... (00:57:05)
Other mistake: In the beginning of the song about Augustus Gloop, computer generated Oompa Loompas can be seen running through the Chocolate Room, preparing to sing their song. In the DVD release, some Oompa Loompas can be seen running to places that no real person could possibly stand on. This mistake was later corrected in the Blu-Ray release.
