Incorrectly regarded as goofs: Aldo makes reference to Little Anthony and his Imperial. While we take this as an anachronistic reference to the doo-wop group, he could have meant it only as a reference to the car, so it's not wrong for him.
Continuity: When Snaps slams Anthony on the table his hands are on his shoulders, in the next shot his hands are around his neck.
Continuity: When Dr Poole (Tim Curry) arrives at the Provolone mansion, Anthony Rossano (Vincent Spano) is just about to leave. He never says a word during this scene, but Dr Poole comments on Anthony's hometown based solely on his accent. This couldn't happen without Anthony actually speaking.
