Continuity mistake: The amount and position of the blood on Amsterdam's neck changes during the first fight with Jenny after he discovers she's a turtledove. (00:49:05)
Continuity mistake: Jenny pokes Amsterdam with her knife on the right side of the neck as he is trying to retrieve his medallion from her. Shortly afterwards, while walking back with her, he is seen dabbing the left side of his neck in two different shots, one of them pretty lengthy. (00:50:00)
Continuity mistake: When Amsterdam just met up with Jenny after she stole from the house, he is holding a handkerchief to his neck were he was cut. Then the camera view changes and his arm isn't there and it was too quick for him to move his arm. (00:50:20)
Continuity mistake: When Amsterdam is walking through the streets for the second time with Bill, Monk knocks Amsterdam's hat up so he can see his face. When he hits it up, the hat goes up on Amsterdam's face. Then they show Bill, then Amsterdam again, and the hat is back down shading his eyes. After a shot of Monk, they show Amsterdam again, and the hat is back up away from his eyes. (00:53:30)
Continuity mistake: When Jenny rubs her fingers over the old scars on Amsterdam's chest, you can see light under the tips of the scars as if they peeled up. (01:05:50)
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)
Continuity mistake: When Amsterdam jumps at the killer to protect Bill, the way he takes off to the right and the way he grabs the hand with the gun coming from the left side don't fit. (01:13:40)
Continuity mistake: When Bill gets shot, he is standing above the man who shot him and depending on the camera angle, the blood spot on his left arm changes size and location. Happens about 4 times during the scene. (01:14:45)
Continuity mistake: After saving Bill, Amsterdam makes a toast and puts his hand on his chest. Camera angle changes and his hand is by his side. (01:19:55)
Continuity mistake: After the party following Bill's attempted murder Jenny walks up the stairs. Amsterdam runs after her immediately to confront her, and when he storms into her room she is in the middle of cleaning Bill's blood-stained clothes. Besides, there's no water in the bowl. (01:20:30)
Continuity mistake: When Jenny and Amsterdam are lying in bed Bill suddenly sits in a chair next to the bed. He has an American flag draped over his shoulders. The way the flag is folded on the stars side changes when Amsterdam asks him if his shoulder is keeping him up, without Bill changing position. (01:22:45)
Continuity mistake: When Amsterdam and Jenny continue talking after Bill has just left them in the bedroom, Jenny's hands keep shifting from both hands on her chest to just one hand between shots. (01:28:45)
Continuity mistake: The level in the Butcher's drink changes from shot to shot during the celebration of the defeat of the Dead Rabbits. (01:40:25)
Continuity mistake: After Bill throws the knife at Amsterdam, he is seen walking up to him and when the camera angle changes he is seen at twice the distance from Amsterdam then he just was. (01:40:55)
Continuity mistake: When Amsterdam tries to kill the butcher and fails, the butcher straddles Amsterdam on a table and tosses a cleaver in the air. The cleaver rotates counter-clockwise so that the blade is rotating backward; however, when the cleaver lands, it is rotating clockwise so that the blade sticks into the wooden table. This would be impossible the way the cleaver is tossed into the air with a back-handed flip. (01:42:15)
Suggested correction: It is possible, if it falls quick enough. Doesn't matter where it rotates, if it is blade down at the moment of touching the table - it will stick.
Continuity mistake: In the shot when Amsterdam is lying on the table and Bill's cleaver is rotating in the air you see that he is wearing a checkered black-and-white scarf. This wasn't there before, and it's gone right after, and it would have been visible the way he was manhandled by Bill's men. (01:42:15)
Continuity mistake: After Amsterdam gets almost killed by Bill, Jenny is tending to him in a cave. She leans over him to kiss him, and while she does so a scarf that she had around her shoulders disappears. (01:44:05)
Continuity mistake: When William "Boss" Tweed tries to win over Amsterdam, he hands him a newspaper that covers the events at the church of the previous day. In the next shot Amsterdam's hands are rested in his lap and the paper is nowhere, and the following wide shot confirms that he hasn't dropped it on the floor. (02:03:00)
Continuity mistake: When Monk gives an election speech we see Amsterdam and his buddies standing at a distance in front of a house. When the camera angle changes in mid-sentence Amsterdam is standing in the first row of the audience. (02:05:25)
Continuity mistake: After Jenny gets mugged at the dock, the shot shows her pulling herself to a standing position on a crate. In the next shot, from farther back and up high, she is crawling over to the crate she just pulled herself up on. (02:20:55)
