Other mistake: Even though it is snowing throughout much of the movie, none of the snow seems to stick to any of the characters' fur. Even during the fight scene when they are rolling around in it, they are never covered with white.
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 Sonic and Tails are fighting metal Robotnik, he shoots glue at Tail's tail. Tails says he can't fly to help Sonic, but when he gets the piece of concrete to surf across the water on you can see that his tails are not glued together.
Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.
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.
Factual error: During the opening credits, the show's copyright date is shown in Roman numerals as MCLXIV. In Arabic numbers, that's 1164 - it should have been MCMLXIV for 1964.
Factual error: In the movie, we see the Statue of Liberty with its current bluish-green color. The statue only got that color over time, and as it was still being built, it should be its original brown.
Continuity mistake: When Rapunzel wraps her hair around Flynn's hand she does so six to seven times. When the camera pans to the hand, it shows a criss cross pattern. That would require at most, 2 or 3 times, of wrapping the hair around.When the glow of the hair reaches Flynn's hand, the hair is wrapped in a straight formation. Then when the hand is healed Flynn unwraps it, with no more than one to two revolutions of wrapped hair.
Factual error: In "Pikachu and Pichu," when Pikachu and the Pichu brothers come to the big play structure thing, there are a bunch of Pokemon around, including a red-and-white, ball-shaped Pokemon called Voltorb. The dubbers for the English version made a very noticeable error here: instead of Voltorb saying "Voltorb," (almost all Pokemon say parts of their names when they speak) it says "Electrode," which is the name of a similar-looking, but different Pokemon. The two are both red and white, but the difference is that Voltorb has eyes on the red part of its body, while Electrode has eyes on the white part of its body.
Character mistake: One of the other trainers said he rode over on a Pidgeotto, but it was a Pidgeot.
Continuity mistake: When the evil king's female assistant is "turned into" Odette, and Prince Derek is dancing with her near the end, he puts the locket on her. The chain goes around her hair, and in the next shot, it's under her hair. They were dancing the whole time, so how could she or Derek have pulled her hair out of the chain?
Continuity mistake: As paramedics inflate Jordan's assistant Stan Podolak following his lone bucket, the scoreboard shows the Monstars ahead 77-67 with 10 seconds remaining. Yet following his treatment and the surprise entrance of Bill Murray, the score has changed to 77-76 with no time having elapsed.
Continuity mistake: When they are in the Whitehouse, and Beavis has turned into Cornholio, he picks up the "Red" hotline phone on the President's desk, and is talking to the nuclear bomb officials. Later, when they are in the President's office again, getting their certificates, there is now a black phone on the desk, where the red one was. (01:03:05 - 01:11:00)
Continuity mistake: In the third segment of the movie we see Davis, Yolei, Cody and their Digimon playing on the beach. In the wide shot when we see all of them playing we see that Davi's Digimon is in his "rookie" form, Veemon. When they show a closeup of him and Davis together, Veemon is now in his "in training" form DemiVeemon. Then they show them all playing again and he is now Veemon again.
