Factual error: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in, despite that trash having been compacted. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a densely compacted cube.

Suggested correction: You haven't noticed the exact shape of his body. The back sticks out a tad. Garbage fills the space and the back pushes in to compress it.

Continuity mistake: When Shifu performs the Wuxi finger hold on Po, in one shot, we see all of Po's fingers, except the one Shifu is holding, are closed to his palm. In the next shot, all his fingers are open. (00:22:05)

Suggested correction: If you slow down before the part where the camera pans onto Po when he's surprised, his fingers open.

Factual error: In the opening credits, Lewis Carroll is spelt incorrectly, as 'Carrol.' (00:00:30)

Continuity mistake: In the scene where Chicken Little lends the alien baby, Kirby, his handkerchief, after Kirby blows his nose, it sticks to Chicken Little's hand. Chicken Little then wipes the hanky off his hand on to the grass. In the very next shot, the hanky has disappeared, and never shows up again.

Plot hole: The whole plot of the first "Brother Bear" was that Kenai had to go to that mountain to become human. But at the end of this movie, the spirits were about to change Kenai back into a human in the middle of a cliff, which makes the entire first movie completely pointless.

Continuity mistake: In the battle scene at autobot city, Megatron orders Soundwave to jam the transmission that Blaster is sending to Optimus Prime. When Soundwave ejects Rumble, Frenzy, Ravage & Ratbat we see them flying through the air transforming simultaneously and and both Rumble & Frenzy are coloured the same (red & black) when Rumble is supposed to be purple. (00:15:08)

Continuity mistake: When Pleakley is tipped out of the chest, he is accompanied by lots of Lilo's toys. When Stitch activates the pod, the toys have vanished from the floor around Lilo and Pleakley's feet. (00:15:15)

Continuity mistake: When Ralph sticks Sour Bill to a candy tree, the branch is directly under Sour Bill, but when Vanellope has become a princess later on, the branch is now facing Sour Bill's right. (01:13:00 - 01:28:15)
Casual Person
Continuity mistake: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer, and the lid is back on. (01:29:00)

Other mistake: Whenever Verne is inside his shell, he has a tail (and references to it "tingling" are made throughout the movie), however, when he is out of his shell he has human-style buttocks and no tail.

Continuity mistake: Following Rodney's step from the escalator on the red pedestal he is being scooped into one half of a wire-frame globe/ball. Two halves now (the other one has Fender in it) form an intact globe. A safety bar with a 'wooden' middle bit (like those on rollercoasters) suddenly appears. After their journey, when the ball splits back into two halves, the safety bar, which previously had mysteriously appeared, now has disappeared.

Revealing mistake: The stepmother's arm disappears for a split second when she tells her daughters that there is still a chance for them to become the princess.

Continuity mistake: When the matchmaker grabs Mulan's hand her palm is shown to be covered in ink. She then unwittingly paints herself a goatee. However, immediately after this she grabs the teapot's handle but no ink rubs off onto it. The ink miraculously disappears from her palm as well.

Continuity mistake: In the scene at the Rangers Station, the tuning dial on the radio disappears and then re-appears.

Audio problem: In the scene where Simba is being attacked by Zira and the other outlanders, he rolls down a small cliff. Zira then says, "Yes, we've got him", but if you watch her mouth she is actually laughing and her mouth isn't moving at all.

Continuity mistake: When Bernard and Bianca arrive at the airport, and wait for Orville, Bianca removes her coat. Yet when we see her through the window, her coat has reappeared and it then vanishes again. (00:25:15)

Continuity mistake: While Megamind is in the Metroman Museum, he uses his dehydrator gun and turns Bernard into a little blue cube. He puts the cube in his pocket, then picks up Bernard's cellphone and glasses.At the end of the movie, inserted into the credits is a short scene where Minion is doing laundry. As he approaches the washing machine, Bernard pops out of it, having been rehydrated in the wash - with his glasses perched askew on his head. (00:30:05 - 01:28:20)
