Continuity mistake: Sometimes Shrek's front door opens outwards, at other times inwards, yet it can't be "two-way" because whenever it closes, it slams against the frame. (00:10:55 - 00:13:45)
Continuity mistake: As Buddy walks out into the street at the start of the movie when the cat is playing dead, you can see several parked cars on the street behind him. When the van backs up to 'catnap' buddy, there are no parked cars. Then as the van drives off again, there is a different bunch of parked cars in the street. (00:03:54)
Continuity mistake: When Dr. Dolittle is giving CPR to the bear, the bear is completely dry. If you just rescued something from the water, it should be wet. (00:35:30)
Visible crew/equipment: During the Quidditch match Harry's broomstick tries to shake him off, due to the spell. After Hermione tells Ron, "Leave it to me," in Harry's last close-up before he flips over, the seat that is attached to the broomstick, to make it more comfortable for Dan Radcliffe to sit on, is entirely visible. Glimpses of other seats can be had during the match as well. (01:20:50)
Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.
Continuity mistake: At the big dinner, Clarisse tries to show the Japanese man some pictures and he shakes his head as he eats his green soup. A minute later, they serve the green soup.
Continuity mistake: When Juni handcuffs the metal box to his wrist, it switches back forth from his right wrist to his left over and over again. (00:35:05)
Audio problem: On the first level of the video game, after Velma brings up what she remembers what Eric said about the Scooby snacks in the game, you hear Daphne talking but you see Velma's lips moving. (00:01:00)
Other mistake: When they are playing polo on the field one guy scores a goal then when Mary-Kate scores the goal it is the same shot - the guy on the horse is in the same place during both shots.
Continuity mistake: When the family is at the funeral home and the audience can see the casket, it has a picture of angels riding up to heaven. It is very colourful and eye catching, but at the church during the actual funeral, the casket has all red cloth covering the inside of it.
Continuity mistake: When Sulley places the menu on the table he puts it face down (logo first), then when he lifts up the table, to quickly get Boo, the menu is face up. (00:26:05)
Visible crew/equipment: When McGoogles attacks McGinty in the gym, the shadow of a crew member catching the McGoogles suit is visible against the wall.
Continuity mistake: Kamaji bangs the work surface, causing a chopstick to fall to the floor, but in a following shot both chopsticks are back in the bowl. (00:23:00)
Continuity mistake: Nick's necklace is a string looped through a ring, but sometimes the string makes only one pass through the ring and sometimes two.
Other mistake: In the beginning, the girls arrive at the airport in Chicago and you can see a billboard in the background. Then the credits roll and they land in the sunny Bahamas and as they are driving away in the limo, the same billboard can be seen in the background. Guess they were on a tight budget and had to computer generate the snow over a scene filmed in the Bahamas.
Continuity mistake: There is a scene when a girl knocks on the door of the house of her friend. She opens and in the background you can see another girl doing nothing. The shot later she has disappeared.
Continuity mistake: When TJ jumps in the dumpster at the school to hide from the guys in suits, he sees two guys and another who's dressed up like Principal Prickly in his normal shabby suit, but then a second later when he takes off his Prickly mask he's in a black suit.
Continuity mistake: When Mario walks out of the bus station to meet his auntie and cousin, he is holding 3 bags. 2 rucksacks and a sports bag. The sports bag is all black. When he arrives at his auntie's house, he takes his bags out of the trunk. The 2 rucksacks are the same, but the sports bag has gone from all black, to red and green. (00:45:10)
Other mistake: When Stephanie (the kid's mom) gets sprayed with mud by the bus, it is accelerating as much as it can in reverse. Why would it accelerate so much in reverse if it's trying to avoid falling down the hill?
