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.
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.
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.
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.
Visible crew/equipment: As Doric leaves the house after transforming from a cat, a crew member can be seen in the background. The crew member is casually leaning against a wall, with a red T-shirt and a face mask. (00:41:18)
Suggested correction: This person is a tiny figure on the extreme right of the screen who is on screen for a fraction of a second while the camera is panning away from him. I had to watch the scene multiple times before I saw what you are referring to. Even then, he is only identifiable if you freeze-frame the picture, thus invalidating the mistake. (At normal speed, I initially thought he was a red banner or curtain).
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)
Continuity mistake: During the ring scene, the queen tells Eric to enjoy himself, her left arm lowered. A shot later, it's resting on his arm.
Continuity mistake: When in the cyclone stadium scene, you can see two water people behind Gale. But later, a different water person is sitting next to the same water person on the right.
