Continuity mistake: As someone pointed out earlier, the poster for the commemoration of the Five Points battle claims to be the 16th anniversary, but the date shows 1863 -- 17 years after the 1846 battle. To further add to the confusion, when William Cutting is talking to Amsterdam in the bedroom after the night at the brothel, he says, "I killed the last honorable man [Priest Vallon] 15 years ago [in the Five Points battle]." So which is it? 15, 16, or 17 years? (00:02:42)

Continuity mistake: When Amsterdam is in the Chinese ballroom the first time, he shows an unfolded sheet of paper with a drawing to the man sitting across the table from him. In the next shot, he hands the paper - which is now folded - to the man, who then unfolds it. (00:33:30)

Continuity mistake: During the first quasi love scene between Amsterdam and Jenny (after the dance) there is a shot where they begin to kiss, and they are at about the same height, right next to each other. In the next shot, Amsterdam pulls away, and you can see that she was laying back, and he was leaning over her, kissing - a completely different position. (01:07:05)
