Revealing mistake: At the start of the montage in which Frollo ransacks Paris for the gypsy girl, the shot of the three soldiers kicking down the baker's door very briefly places the more distant soldier off to the right "in front" of the closer central soldier; this is a case of incorrect animation cel layering.
Revealing mistake: Right before Dodger walks into Georgette's room in search of Oliver, she talks to herself in the mirror. But at one point the reflection moves when she doesn't. (00:43:10)
Revealing mistake: During the interview, you can see a monitor with the lyrics of "Something", even though he is supposedly improvising.
Suggested correction: This is a deleted scene. It is in the extras on the DVD but it is not part of the movie.
Revealing mistake: In the intro (or one of the intros, rather), they narrate Pootie Tang's origin. A fake newspaper called "New York Pone" is shown, with the front page dedicated to baby Pootie and his invention of a new language. All fun and everything, but the prop is sloppy; you can read below the name of this fake 70s newspaper the URL of the New York Post' s website and the date in April 2001. (00:08:35)
Revealing mistake: During "Never Say Never" Henri instructs Chantal to fly Fievel to immigration where he should be able to find his family. At one point during this shot, Henri's right wing casts no shadow on the Statue of Liberty - only an outline of the wing's shadow is visible. (00:23:25)
Revealing mistake: When Dr Dolittle is talking to the parrot and it raises its left leg, you can see a piece of string running past Dolittle's head used to raise its leg.
Revealing mistake: In the Director's Cut ending when Audrey II eats Seymour, it spits out his glasses, and they land in front of the camera. They pulled this off by having a pair of glasses inside the plant's mouth that would be yanked out by a string, and another pair of glasses would be dropped in front of the camera. However, the first pair gets caught in the teeth and fall back inside the mouth, but the other pair lands on the ground anyway.
Revealing mistake: Near the beginning of the film, when Clang is outside the Beatles' flat on his delivery bike, you can plainly see the rope tied to the front of it giving him a pull as he starts to ride off. In the next shot the rope is gone.
Revealing mistake: When Woody and Sharon are singing their 'Ol Devil Moon' duet, Sharon starts to sit up, but then the shot suddenly changes to them both sitting up, Woody in a fade behind her as she sings.
Revealing mistake: Tommy picks up a chair and breaks it on a desk, but the chair breaks just before contact. (01:25:30)
Revealing mistake: A scene in which a group of soldiers appears to be running uphill was obviously filmed with a tilted camera because all the trees in the background are leaning at a 65-degree angle.
Revealing mistake: When we first see Oliver Reed, we see his shadow first on the wall at a ramp to the pub. As his shadow spreads its legs, we then see him spreading his legs a moment later. Shadow puppetry was used by the director to give the audience the impression that he is ominous and foreboding before we ever see the man himself. (00:54:10)
Revealing mistake: During the fight, Popeye ducks Oxheart's swings. If you watch carefully, it appears to be the same swing repeated multiple times from different angles.
Revealing mistake: Whenever Stupid Bat is flying, the wires pulling him up are visible.
Revealing mistake: During the fainting scene number of the extras can be seen waving and looking at the camera.
