Audio problem: When singing Reproduction, a boy sings "Oh I think I'm gonna throw up"; yet he sticks his finger down his throat and keeps it there until the line is over, never closing his mouth; how did he make the 'p' sound on 'up' without closing his lips together? The words are pronounced very clearly and the camera doesn't cut from his face until after the line is done.
Audio problem: When Mary is reading Peter Pan to Gertie, her shadow's lips don't match up with the words she is saying.
Audio problem: When the Stuka 'bombs' the bunker that Pink's father is in, we see it pass overhead, making the unique Stuka 'scream'. Then we hear the whistle of the bomb as it falls to earth, yet we still see the bomb is attached to the underside of the Stuka. The Stuka shown carries just the one bomb, so it isn't another one that is falling. The truth is that this Stuka is a remote-controlled miniature that did not have the ability to release its fake bomb, and the editors failed to avoid using the whistling sound until this shot was over.

Audio problem: After Spicoli crashes Jefferson's car, Jefferson's brother says "My brother's gonna kill us - he's gonna kill us" yet his mouth isn't moving during those lines (even though shown from the back you can still tell). Then camera faces him and he now matches the words.
Audio problem: When the children are washing clothes, Auntie Shrew reacts by looking up towards the sound of the rat's moving equipment, a second before it is heard.
