Character mistake: In the beginning of the film, Oliver has been brought by Mr. and Mrs. Bumble to the Governor's door after asking for more to eat. Mrs. Bumble then sings, "They'll lay the blame on the one who named him," and as Mr. Bumble is responding, "O-li-ver", look at Oliver. He is completely spacing out and not in character at all - staring off into the distance and flicking his tongue in and out of his mouth.
