Other mistake: In the beginning of the song about Augustus Gloop, computer generated Oompa Loompas can be seen running through the Chocolate Room, preparing to sing their song. In the DVD release, some Oompa Loompas can be seen running to places that no real person could possibly stand on. This mistake was later corrected in the Blu-Ray release.
Other mistake: When Sarah is at her Aunt Mitzi's house looking at the yearbook picture of Beau Burroughs, Beau's name appears on the top of the list, yet his picture is farthest to the right in a row of pictures. Yearbooks list names with the top name being on the left, and the last name on the right.
Other mistake: When the NASCAR pit crew starts working on Herbie at the barn, they initially pull a bunch of parts and tools from their racetrack trailer. One man is carrying a distinctive VW-only wheel rim, which would definitely not fit their regular NASCAR car. The decision to race Herbie had just been made, so they would not have been carrying VW spare parts yet. Nor could they have pulled one of Herbie's wheels yet since they were still carrying the jack to the barn.
Other mistake: In the championship game, the Yankees batter hits a foul ball when they score their winning runs.
Other mistake: When Alex, Marty, Gloria and Melman are talking together inside the boxes, Alex has three holes in his box allowing light in for him. Melman, Marty and Gloria have that too, but Gloria's box is lying under Alex's and Marty's, so it can't get as much light - but it does.
Other mistake: During the scene where Charlie is watching the horror movie on TV and Viola sneaks up behind her wearing the costume with the long finger nails and scares her. They show a shot from Viola's point of view and you see Charlie sitting on the couch from the back, but the TV is not on.
Other mistake: When Chris and Jamie are sitting on Jamie's bed, Tim comes in and shoves Chris onto the floor. This is supposed to be when the yearbooks are switched, but if you watch closely you will notice that Tim leaves with the same yearbook he brought in. (00:03:50)
Other mistake: During the opening credits (right after the fish chopping shot) two bearded gentlemen meet in the street. As they part, Lord Barkis suddenly appears behind them. But where did he come from? He didn't walk in from either side, we would have seen him. Nor was there any door he might have come through.
Other mistake: When Shane crashes the car through a fence (or wall), it appears that the car sustained absolutely no damage on the front (or anywhere else as far as I could tell). Later, there seemed to be very little damage to the car as a result of a chase scene where the car hit things, just a relatively minor scrape or two.
Other mistake: When Dorthy is trying to audition for the Muppet's the man says they are gone and the Muppet's bus pulls up. If you look when the bus is pulling up there is no one in it, even the driver seat is empty. Then a few seconds after the bus stops Kermit and Miss. Piggy come walking out.
Other mistake: When Percy and Simon are driving to the hotel and it starts to rain, the rain is dripping downwards on the windshield. Normally when a car is driving the rain should be moving up (because of the wind).
Other mistake: When the two heroes are wind riding the plane they more or less repaired (about 1 hour and 30 minutes from the beginning of the movie), the wind blows from the right side of the plane to the left, but the hero is counter balancing the plane on the left side as if the wind were coming from the left. He should be standing on the right side of the plane to really balance it.
Other mistake: When the family goes to the hardware depot to obtain home improvement materials, the twins manage to imbed the tines of a fork lift into a display of bagged sand over the Admiral's shoulders, yet the entire contents of the ripped bags drizzle down higher, onto his head.
