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. (00:39:00)
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: While the wizard is speaking near the portal, a ghost image of him appears to the left.
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: Lightning Mcqueen is trying to become the first rookie in Piston Cup history to win the Piston Cup, but Doc Hudson won the Piston Cup in 1951 the first year that Hudson Hornets were produced, which also would have made him a rookie.
Other mistake: When Costigan drags a handcuffed Sullivan into the elevator, Costigan slams Sullivan against the wall and his left arm is visible and not in handcuffs. (02:13:05)
Other mistake: Near the end of the movie, after the cops storm the bank, all the cops walk into the vault, and as the camera follows them into the vault, you can hear the camera hit the metal vault door, and visibly see the camera shake from hitting it. (01:38:15)
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: When Ricky is pinned to the table and has his arm broken by Jean, he has the bone between his elbow and shoulder broken. However, when they show him trying to saw off the cast with a knife, it ends right above his elbow.
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 Larry takes Jed back to his miniature city, in the shot where the T-Rex almost hits Larry, watch Teddy's' horse. His head moves, following Larry and the cameraman. This cannot happen as the horse and Teddy had been already transformed into statues. (00:42:00 - 00:43:00)
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.
