Revealing mistake: Lizzie has black nail polish and the same size of nails throughout the entire movie. Supposedly, Lizzie and Isabella are different people. But, when Isabella comes back, you can see she has the same color nail polish and the same size of nails as Lizzie. I don't think it's just a coincidence.
Revealing mistake: At the bank there is a close-up of Mr. Darling with Sir Edward Quiller Couch standing behind him to his right, just as Nana, et al. are about to collide with the bankers. The camera pans in for the extreme close-up of Mr. Darling, who makes a horrified face. Later, when the Darlings are at the party Nana bursts in. Sir Edward again stands to Mr. Darling's right. Mr. Darling puts his hands up in front of himself and the next close-up shot is the very same shot from the bank. Part of Sir Edward's hair is edited and the background is digitally augmented. (00:09:25 - 00:23:20)
Revealing mistake: In the scene where Trout's gang burns the school and kills Sam, there is a part where Katherine runs into the sheriff's office then exits. A few seconds later, Katherine runs by a shop on which the name is reversed. Very obvious. (00:51:40)

A few seconds go by before the shot goes back to Mr. Kubitz - plenty of time for the car to have driven out of shot. But when Mr. Kubitz is shown at the doorway again, the car is still there, driving along.
Revealing mistake: In the beginning of the movie, there is a scene where Buddy hits his head on the roof of the house as he's running out. You can obviously see a machine pushed the snow forward to land on his head. [May be easier to see in fullscreen version]. (00:12:40)

So what pulled him back?
Revealing mistake: Rex the dog leaps through the protective wire netting around the baseball practice area. As he jumps through, you can see the netting split apart and that the edges of the 'broken' wire mesh are protected with some duct tape.
Revealing mistake: At the end of the movie when the Grandpa and grandson are tackled after being given the 'fortune cookies' right at the moment of impact the little boy has been replaced by a stunt double which is a grown man dressed in the same clothes.
