Continuity mistake: Towards the end of the movie, Kamala asks Carol on the porch, "Hey, do you still fly that thing?" She is holding her right hand with her left. The camera angle switches, and her left hand is low, out of frame and comes back up only seconds later after Carol's answer.
Other mistake: In the Special Thanks section, Bobcat Goldthwait's name is misspelled as "Goldthwaite." (02:28:28)
Continuity mistake: When Coriolanus and Sejanus are eating lunch at the Academy, Coriolanus' sandwiches switch positions several times, stacking and unstacking, and turning several times.
Factual error: Kat morphs by calling for the Pterodactyl but she wasn't a ranger when the Pterodactyl was in use, she became the pink Ninja Ranger so her call should have been, "pink ranger power!"
Suggested correction: It's explained in the movie. Alpha made proxie power coins, in order for them to access the dino powers. She was given the Pterodactyl coin and the dino powers to get Tommy, Jason, and Kimberly back.
Continuity mistake: Before Francois writes on the whiteboard (dry-erase), the words at the top are not boxed-in (or underlined). After being boxed-in, the words are surrounded by more of an oval shape, then not highlighted at all - but the words on the third line are boxed-in, followed by being underlined 4 times, to not underlined, to being boxed-in again. (00:17:28 - 00:19:05)
Factual error: The storm chasers are meeting by the road and you see the sign for I-90 East in the background several times. This movie takes place in and around Texas, yet the route that I-90 takes is nowhere remotely close to that far south.
Audio problem: At the start, when at Ground Zero, a robot wakes up, and Joshua shuts it down. The woman he's with says, "What the hell," but her mouth says, "What the fuck," dubbed presumably for a lower rating.
Continuity mistake: The position of the pamphlet display on the side table changes a few times after Paul sits on the couch. The pamphlets are near the upper right-hand corner of the table before Paul sits, and then the pamphlets are behind the lamp, towards the rear-center. The pamphlets are in the upper left-hand corner, then suddenly in the upper right-hand corner (where they start) when Paul removes one from the display. The location and angle of the lamp shade also vary. (00:09:00 - 00:09:25)
Continuity mistake: In the rear view of the picture frames on the desk, the frames are closer together and aligned in a somewhat semi-circular pattern, but are spread out and staggered in the front view. At first, it appears a gap in time can possibly explain the rearranged frames (Rock is opening mail), but a rear view while he is still reading his mail shows the frames arranged like they originally were. (00:03:25 - 00:03:51)
Factual error: Lieutenant Commander Sharp addresses the crew of the USS King. At the end, he shouts "Semper Fi." Marines say "Semper Fi," not Navy personnel. "Hooyah!" would have been more appropriate. By the way, I don't think bright metal collar insignias are worn with the blue camo uniform. They use subdued rank insignia. But I am not sure.
Factual error: Professor Alessando steals the keys from the ward. One key is under a copy of the Italian magazine "L'Eternauta." However, it is issue #103, released in November 1991. The movie is set one year earlier, at the end of 1990.
