Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.
Other mistake: At the very beginning of the movie, when the guy throws the match into the house, it doesn't enter through the window. The match crashes and bounces back, but the fire inside the house still occurs. (00:02:40)
Other mistake: Meowth calls one particular Pokémon in the test tube-thing a Sandshrew, however it is a Sandslash. This is a dubbing error, as Nyasu (Meowth's Japanese name) correctly identifies the Pokémon as a Sandopan (Sandslash's Japanese name) in the original Japanese version. (00:58:26)
Other mistake: The knife used in the Argentina pub scene never has any blood on it, despite being driven into one man's stomach and another man's hand-twice.
Other mistake: The fire truck passing by Nani on the way to her destroyed house has the same license plate as the gas truck that Stitch hijacks.
Other mistake: When Warren/Angel refuses the cure and spreads his wings, he is looking to the left of the screen at his father. In the reflection of Dr. Kavita Rao's glasses the shot of him is not reversed; he is still looking to the left of the screen when he should in fact be looking to the right. (00:33:00)
Other mistake: Davis tells Kate to go and she jumps out of the falling plane, her chute opening. Davis then takes a minute to free Harvey from the plane as it's still falling before they both get out. Once they are free falling he takes a few seconds before he pulls their chutes as well. However as they are coming down close to the plane crash site, Kate is near level with them in altitude as they are all coming down together. With how high she was when she jumped out compared to the time it took for Davis and Harvey to get out of the plane and open their chutes, she would have been several minutes behind them in the sky, not right next to them. (00:47:45 - 00:49:05)
Suggested correction: She jumped first and would have already descended in altitude. Then the guys jump and freefalled and pulled their chutes so it is plausible they caught up to her altitude when their chutes opened.
Other mistake: When Dr Grant and the children reach the perimeter fence, Dr Grant tries to see if he can fit through, to no avail. When he and the kids start to climb, however, it is quite obvious that both Tim and Lex would have been able to crawl through quite easily, and that only Dr Grant should have had to climb over. Partly this links to the mistake here, where the holes in the fence are much bigger in the first shot, then when he tries to widen them he's holding a different part of the fence where they're smaller.
Other mistake: In the scene at the beginning where Phil eats Jason's Heart, you'll notice that he screams like a monster for a bit. Don't you think that the two security guards would easily hear the screaming and intervene, being that they're in the very next room? (00:13:40)
Other mistake: When the monk arrives with Jackson and the others at the gate leading into the secret entrance of the ships, the countdown to impact timer reads about 28 minutes. It is highly implausible that the group, which contains elderly and small children, are able to get to the top of what looks to be a 100 story staircase in less than 15 minutes without breaking a sweat. Once they are inside the hatch, the countdown to impact timer reads about 13 minutes.
Other mistake: When Prot visits the doctor's house, he thanks the wife and the camera is zoomed into his sunglasses. The reflection of his glasses shows the doctor looking at him, but the doctor is standing behind him. (00:53:40)
Other mistake: After realising they can track the mother box, Batman says they have to go back to his base to use one of his satellites to track it, and they all do so. Which completely ignores the fact that Cyborg could easily access the satellite feed directly using his abilities and display it to the others on any nearby screen in Star Labs.
Suggested correction: Just because he had many options available to him, does not mean that the option which he chose was wrong.
Other mistake: When the general passes the clipboard to the President to sign the nuclear release, the clipboard is actually upside-down. (00:55:55)
Other mistake: When the goons car is carried off to sea by the helicopter, Bond can watch the helicopter on the screen in Aki's car. But where is that camera mounted? On a camera plane?
Other mistake: When the autoguns fire at the aliens for the second time, there is a flashcut of an alien being blasted apart. Watch closely; it's the same clip of the alien that Vasquez shot and subsequently sprayed Drake with acid. (01:18:00)
Other mistake: In the scene after Arnold kills the construction hoods he goes home to Sharon Stone and tries to convince her that it was real by showing her his bloody hands with which he was grabbing her shoulders, yet there is no blood on her or the appliances he turned off upon entering the apartment.
Other mistake: When Truman is standing at the open doorway at the very end, and is addressed directly by Cristof, during some of the shots, the open doorway behind him becomes a black backing board, visible from the way the light falls on it. (01:32:15)
Other mistake: In the scene where Ripley throws the basketball at Johner, Christie says to Ripley, "Ok, I've got a new game, tag .." He hits her with the handles straight in the face once, he misses the next shot, misses again, and Ripley hits him to the ground, but you neither see or hear the handles fall. (00:23:15)
Other mistake: The alien that comes out of the dog is a lot bigger than the actual dog just seconds after it appears. This only applies to the theatrical version, as in the extended version the alien comes out of an ox.
Other mistake: During the beginning of the freeway chase scene, a "Maximum Speed 65" sign can be seen along the freeway wall in the slow lane that is facing the opposite direction of traffic. Freeway traffic in that lane would only be able to see it in their rear-view mirrors. (01:25:20)
