Other mistake: A.J. gets dirt on his face although he is covered by an astronaut's suit.
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: 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: At the taxi cab chase at the end, you can notice when the car is a real one and when it's CGI. Note how the real car has scratches and other things on the front of it, but the CGI car, if you look closely, has almost no imperfections, and even if it does have some, it doesn't match the real car one bit. You can see these things when the car drives off his mouth or when you see Godzilla running behind.
Other mistake: After they kill the alien/teacher and leave the school they pass one girl in a blue/green tee-shirt with a waterbottle. Just one scene later you see this girl again under a tree, suddenly in front of them.
Other mistake: Frank visits Walenski just before the tuning, but the clock in his house says it is 1 o'clock. (00:27:17)
Other mistake: When Data discovers the holoship in the lake he reduces the amount of water in the lake significantly (The ship is now clearly visible, standing out several meters). But even so the banks and the landing stage are still in their correct position. If the surface level had been reduced the landing stage should have been standing out of the water, too.
Other mistake: When Jackie is falling through the trees at the beginning, you can easily tell he is on strings because he would hit the branches with a lot more force than he does, and also wobbles in certain ways which would be impossible to do in this situation.
Other mistake: How can it be named Wolf-Beiderman? Wolf never sent the email, and even if it did go, once the network was restored, he never called it Wolf-B before writing it on the floppy label. The president says both were killed in the crash. So, they invent an astronomer working at the observatory and no one notices? Remember, the floppy was destroyed in the fire. Wolf never called anyone; he was killed while trying to make a call. Maybe the pics were also burned. Mr. Perry never followed up?
Other mistake: They're meant to be on rebreathers (they recycle the air around the system, so you 'rebreathe' it), yet in the u/w scenes, it can be seen that they're on open circuit systems, i.e. conventional scuba, as they're venting exhaust gases. Rebreathers do not release bubbles in the quantities shown.
Other mistake: When Chip Hazard's chopper is shot down, he jumps clear before it goes down. But he jumps up, and at the height his leap takes him, he should get his head chopped off by the rotors.
Other mistake: Jack is rescued by Bridget at the train station where he is being pursued by Sandra (an alien). Bridget shows up in her car and drives him away so Sandra cannot catch him. But Sandra and Bridget have never met. How could she know Sandra was a threat? Even more confounding, how did Bridget know to find Jack at the train station? He was randomly thereafter jumping out of the car he was being abducted in. (00:50:30)
Other mistake: When Bruce Wayne is searching the database after the nurse leaves Dick's room, the screen initially has the vital stats (height, age etc) of Nora, Mr. Freeze's wife. (00:32:00)
Other mistake: When Cain's eye is damaged in the fight the officer says he will only be good for cannon fodder, with no depth perception. So how can he be driving an armoured vehicle?
Suggested correction: He has been given a replacement eye, which takes care of the problem. He's just angry because Caine 607 didn't win perfectly and showed weakness by being out thought.
Other mistake: In the scene where Vir gets in a fight with Zack you can for a moment see the Rolex that Stephen Furst is wearing on his right arm. (01:21:10 - 01:21:20)
