Other mistake: The rope is wound round Jack's body and the pole at his back numerous times. When Shishka-Jack falls, the pole gets jammed between the cliffs, but the pole does not break and the rope does not tear. The rope that goes round the pole numerous times simply disappears, leaving the rope intact around only Jack's body in order for Jack to twirl and unravel as he falls.Super Grover
Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.
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)THGhost
Other mistake: When Joey Lawrence gets his hand cut off by the human, he wakes up to find his arm where his hand used to be wrapped in some kind of black cloth. It's obviously his hand that is wrapped up because the wrap sticks out too far to be only wrapping his wrist. Plus it is also bulky which gives away the hand underneath.
Other mistake: Every time somebody climbs to the attic in the "lake house", you see a small, dark, enclosed chamber with some abandoned stuff. However, as soon as you see the "lake house" from the outside, it is a single-level construction entirely made of glass, with no inside staircase or ladder, and three smaller glasshouses on the roof. There is not a single wooden panel to enclose the attic, nor any construction in the house that looks like it could be that attic.
Other mistake: Throughout the movie we see the mustang rolling chassis in the garage. This is a rolling chassis of a 1967 Shelby mustang gt 500/350. The main ways to realize this are that the car has the cut outs in the front for the 2 fog lights that the Shelby had and that the back end has a spoiler which is built into the body. However the car they do all the driving with is a base model 1967 mustang fastback. While a new grille would've covered up the fog-light cutout, the regular fastbacks didn't have the built into the body spoiler like the Shelby's did. Removing the built in spoiler and making it as smooth as it was would've taken way too much time and supplies. It also wouldn't have served any benefit. You could argue they were trying to eliminate down-force on the back but the spoiler was only about 2 inches, it wouldn't have helped. The directors did this to avoid wrecking the much more rare Shelby mustang.
Other mistake: When Bruce and Mos Def are running through the alley near the beginning, they run past a Chinese man who slams a dumpster lid shut. Once Bruce pulls out his gun to look back, that same man starts running because he gets scared. In the next shot, he continues running, but soon stops as if he thinks filming is over. This is visible right before the camera pans to the right.manthabeat
Other mistake: When Haskins and the other coach are going on their recruiting trips in the beginning, we can see the two of them talking on the phone. Funny thing is, that both of them are using pay phones. So who called who? How did they know the number? And how did they know when the other one was going to be near that pay phone? I feel it is highly impossible for one to reach the other when both of them are using pay phones.
Other mistake: In the scene where Mary Lynn Rajskub is driving Harrison Ford around, she is told at the beginning of the scene to "pop the clutch", signifying that she is driving a manual transmission vehicle. However, during the drive, she never removes her hands from the steering wheel to shift gears.
