Continuity mistake: In the beginning of the movie during the skateboard scene with Shaggy and Scooby riding along the conveyor belt, Scooby grabs a hook and both Shaggy and Scooby jump off of the skateboard. You see the skateboard falling off the conveyor belt, but in the next scene it is on the conveyor belt and being crushed. (00:03:20)
Continuity mistake: When Bridget is getting dressed for her big date with Daniel, her tights are over her undies; later, when he's going up her skirt, the tights are clearly under her big ugly undies. (00:17:50 - 00:26:00)
Revealing mistake: A quick mistake happens when Brenda and the girl crawling out of the TV get in a fight. Brenda throws the punch, the other girl falls over, and for a quick second her dress flies up too far and you can see where the makeup (that makes her look dead) on her legs end and you can see her real thigh. (00:25:15)
Factual error: It is stated that Miss Trunchbull competed in the Olympics in shot put, javelin, and hammer throw. According to her jersey those were the 1972 Olympics. The hammer throw wasn't added as an Olympic event for women until 2000.
Continuity mistake: When the house first becomes detaches from its foundation and becomes airborne, Russell is nowhere to be seen, although every angle of the house is shown, including underneath, the front porch and the back porch. He knocks on the door and tells Carl he chased a "snipe" under the porch - but he cannot be seen after liftoff and prior to knocking. The same thing happens near the end, when Dug claims to have hidden under the porch.
Continuity mistake: In the very last scene of the movie where Chris O'Donnell and Renee Zellweger are on the terrace taking their vows, Renee is holding a bouquet. In one shot it is a bouquet of pink flowers, then it changes to a bouquet of yellow flowers and keeps switching back and forth throughout the scene.
Visible crew/equipment: The cameraman is visible in the reflection of window while Holden is walking back to his car in the rain.
Revealing mistake: In the soda shop, the waitress turns off the lights with her elbow because her hands are full, but she misses the light switch by 6 inches. (00:55:10)
Continuity mistake: In the scene just before Miss Piggy and Eileen get fired from the department store, Miss Piggy is watching Kermit and Jenny hug. She then bends a metal pole in half and starts hitting a barrel with it. When she first starts hitting it, the pole she is hitting it with is very thick(much thicker than the one she bent in half), is a different colour and not bent in any way. In the next shot the pole is thinner,longer and looks like the one she originally had, but it is only bent at the top whereas Miss Piggy bent it in the middle. In the next shot of her after that, the pole is now thicker (but not as thick as the first one), is not bent and the colour has changed again. Also if you look around the area where Miss Piggy is, there is only one type of pole lying around, so where did the other two come from? (00:30:15)
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?
Continuity mistake: When Jo's mother and father are in the garden at Jack's house, she gets in her car with curly hair. The next scene shows her driving her car with straight hair.
Continuity mistake: When Felix looks out at the Anfield pitch you can see executive boxes on the opposite stand. He is meant to be in an executive box but can't be, as only one stand at Anfield has boxes. (01:16:20)
Continuity mistake: Gamble and Hoitz get thrown to the ground when the accounting office explodes. In an overhead shot of them rolling around on the ground, Gamble's wooden gun has fallen from its holster and is lying on the ground. Cut to a side shot and the gun is back in its holster. Gamble had both hands covering his ears the whole time, he did not pick up the gun. Then comes another overhead shot, the wooden gun is again missing from the holster.
Character mistake: On the day Rebecca arrives home, Junior Douglas says that he was "Valedictorian, Class of '95." Earlier, Drago talked of almost killing Running Buffalo "during that trouble back in the '40's," which would have been about 50 years earlier. That would mean Drago and McLintock were fighting Indians when they were babies, or possibly before they were born!
