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: When Ian films the Chipettes during the sing-off, he says, "If you like what you see then call Ian Hawke." But when someone else plays the video back later, he says, "If you're interested, then call Ian Hawke."
Continuity mistake: It's shown in many scenes that the robot Gallaxar sends isn't particularly quick moving when it walks. But when it's chasing Ginormica around the city, even though Ginormica is sprinting away, it can catch her far more quickly than its speed would allow. It doesn't suddenly speed up - in the shots when the camera focuses on the robot again, you can still see it moving slowly.
Continuity mistake: During the other father's song, notice the red record player by the door and the position it's in, with the lid facing Coraline when he says, "making up a song". When the camera angle changes and he says, "she's a doll", the record player's position changes completely, with the lid now facing the wall.
Continuity mistake: The poster that Tiana has that her father wrote on says "Tiana's Place." When she finally gets her restaurant, the name is "Tiana's Palace" yet the menus still say "Tiana's Place." (01:29:00 - 01:30:00)
Continuity mistake: In the carnivorous plant scene, Manny grabs the fruit (the bait), which is sitting in the middle of the plant. In the next few shots, the bait disappears and then is replaced with a bulb that housed the red and blue "wires".

Continuity mistake: After the spaghetti twister, Flint puts on his lab coat in the elevator and you can see he has his tuxedo shirt on. Then during the building montage, it's a blue shirt, then changes back to the tuxedo shirt when he turns on the car. Also, during the building, the design on the blue shirt disappears.
Continuity mistake: After escaping Bean Annex on the motorcycle by going off the ramp, Kylie turns back, sees the wolf and does a double take, and tells Mr. Fox "don't turn around". But when everyone looks at the wolf in the next shot when the motorcycle has stopped, they're looking off to the side of the road, not behind them. (01:11:20)

Continuity mistake: When Lex Luthor has his battle suit on and fighting Superman and Batman, the head and neck piece change dramatically and constantly. Sometimes the piece surrounds his head, leaving plenty of room and sometimes his head sticks out over the piece. And it's not a matter of angles, because in some shots, everything being the same, the side piece remains at ear level and his head is either above or below the head piece.
