Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Continuity mistake: In the pool scene where Mrs. Doubtfire picks up and throws a lime at the back of Stu's head, when Stu walks away and the camera goes back to Mrs. Doubtfire at the bar, the lime that she threw is still on the top of the stack of fruit.
Plot hole: After Max and Allison rescue Dani from the witches, Max is driving his parents' car. Winifred flies up along side of them and asks Max to show her his driver's permit. How would she know about driving permits, since she's been dead for 300 years?
Suggested correction: There is a lot the movie doesn't show us about who they've passed and what they heard all evening. One example being we don't know everything the bus driver said to them. It's perfectly reasonable they heard somebody make reference to a driver's permit and the movie did not show us this conversation deeming it invalid to the plot.
Not referring to a learner's permit. She would have known what it means. She's emulating a cop pulling him over. She would have to know what that means...and know the difference between a license and a learners permit. Enough to find it funny and relevant to the situation.
Visible crew/equipment: In the fight scene on the stairs near the end of the movie, the camera shot looks up and there is a security camera mounted up in the corner. (01:29:40)
Factual error: When the shop vac shoots the golf ball at Mr. Wilson's gonads, it only affects him for around ten minutes. The shop vac was able to shoot a glob of paint over 50 feet in the air so the speed and impact of the golf ball would have done much more than put Mr. Wilson in extreme pain for a short while. The impact would have likely caused internal bleeding, swelling, causing him to vomit, probably a rupture, requiring him to be hospitalized. There is no way he is walking away from that, he wouldn't even be walking at all.
Visible crew/equipment: During the scene where the whole family is first driving into Beverly Hills, in the scene where they give the finger to say hello, the camera crew can be seen in the reflection of some of the cars.
Revealing mistake: When the boys' rival team challenges them, all the boys throw their gloves down, except Yeah-Yeah. When they all go to pick them back up, Yeah-Yeah has to pretend to pick it up.
Continuity mistake: When Wednesday and Pugsley are playing with the guillotine, Wednesday has a scroll in her hands, which she then rolls up. The shot changes and you can still see the rolled up scroll in her hands. However, the shot then changes again and you can now see Wednesday rolling up the already rolled up scroll.
Continuity mistake: After failing to catch Sassy, who went down the waterfall, Shadow and Chance are walking by the river bank. In one shot, Shadow's fur is wet, then dry, then wet again.
Revealing mistake: At the end of the decisive game, the bad guy hits a deep foul ball. During that hit, they show the ball against a black background. If you look very closely at the bottom of the screen, you can see a hand throwing the ball.
Continuity mistake: The Pool of Death, as planned by Alex and Katie, has the water in the pool stained with red dye. When Sean slips back into the pool after having just emerged from it, however, the splash seen at that instant is clean water, not red-dyed water.
Continuity mistake: Early in the movie, the kids go moto-surfing and the jeep they are riding in changes from having a door to not having a door.
Continuity mistake: When Regina tells her boyfriend to put the leash on the dog, he goes to do so but when you see his hand clip the leash on, the shot changes to a woman's hand clipping the leash on (the nails are covered in nail polish).
Revealing mistake: The oil lamp carried by Mary when she first finds Colin has a flame that never flickers, and is likely an electric lamp.
Continuity mistake: Just after Huck (Elijah Wood) hides in the piano, Mary Jane comes in to visit her dead brother in his coffin before they bury him. She sets down her candle and in the next shot a chair suddenly appears beside her to sit down.
Continuity mistake: One of the tiles comes loose when Wallace is walking across the ceiling in the museum. A few seconds later, the tile is flat against the wall again.
Continuity mistake: When the Turtles are climbing the wall to get into the garbage-chute that leads to the prison, you can see Donatello's bandana tail hanging down towards the wall just as if they were crawling on the floor. (01:09:05)
Continuity mistake: When Jesse jumps into the pool to ride on Willy's back for the first time he is fully submerged. However, while riding the whale, his hair is dry.
Continuity mistake: When Bob tells Junior that Larry is a cucumber, the carpet and the shadow of Junior's bed shift to the right a little bit.
