Other mistake: At Fagin's place, Bill is supposed to give Nancy a back-handed slap that sends her to the floor, but there's no sound of the slap and there's no contact - it's very badly acted.
Continuity mistake: When Mr Bumble and the female workhouse employee take Oliver to the Governor's office, Bumble raises his hand and knocks on the door. The woman sings "They will lay the blame on the one who named him", prompting Bumble to move his hand away from the door, toward his face, as if he's about to place it over his mouth in concern. The camera then changes angles and Bumble's hand is suddenly lowered and nowhere near his face.
Continuity mistake: At the outset of the song "Who will buy?", the price of roses is "four blooms for a penny." Then it suddenly doubles to two for a penny.
Continuity mistake: During the song "I'd Do Anything" Bet's hair is down and then pulled back, then down again at different parts of the song and dance in that scene.
