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: 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: 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)
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.
Continuity mistake: Look carefully at the brochure Frank has about the Buffalo Chicken Wing festival, the building pictured is the same building as his daughter's school (seen earlier in the movie).
Suggested correction: While the buildings might look similar, they are different buildings. The school has 3 levels with rectangular windows with a pyramid top while the building in the brochure only has 2 levels of non-rectangular windows and more of a dome shape on top.
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: Right after Aki saves Gray and turns around to pick up the canister containing the plant off a table there is no table or ledge. If you watch the movie with the commentary one of the members involved with the movie says that it is floating on nothing. (00:16:50)
Continuity mistake: At the end level, when the gang are in the arcade, the phantom virus makes one of the videos games grab Fred. Some of the wires are red, but when the wires curl around Freds legs, they are all green.
Continuity mistake: In the scene where Rock is trying to destroy Tima and the factory, the side parting in his hair frequently changes sides.
Continuity mistake: Although Clara kicks her shoe at the Mouse King's head, when she gets down from the mantelpiece, it is back on her foot with no sign of her having retrieved it.
Continuity mistake: In Session 24, Faye gets into her aircraft and Ed all of a sudden looks down at Faye, from on top of the roof, and starts talking to her. Look at the back of Ed's shirt, it falls up and goes past her neck and rests at her head, when the camera cuts to a front view, the shirt is above the shoulder line. (00:14:20)
Continuity mistake: When Towa says that Sam should not tell anyone about the Voice of the Forest if he hears about it, her right hand is on her apron, but in the next shot, it is on her robe. Also, the rock closest to the front of her has no crossing of ropes in front of her, but in the next shot, it has one. (00:03:41)
Continuity mistake: In the shot of everyone chanting, "disco ball!" Hermey is seen in the background, but two shots later, Hermey has disappeared. (00:19:00)
Continuity mistake: The arc-shaped garden plant directed the protagonist to someone who can help him. A nasty human armed with shears walks by and starts his torture; he kneels by the plant, in a zone with no shadows, and in the next shot the whole section of ground is in the shade. (00:39:40)
Continuity mistake: When Chiyoko places the blue book as she is moving books around, a part of the pages of a brown one goes from white to brown and back to white.
