Revealing mistake: Iris' taxi stops in front of the Apollo. The street is pretty much empty, but once she is shown getting off the cab, there's suddenly cars, people all over the sidewalk and even in the middle of the road, pretty much everyone looking at the camera crew filming. (00:36:50)
Continuity mistake: In bed, the paper bag Iris gives to the cop has holes in the part of the bag that has no logo. In the corridor, we see his facial features pop from the side with a big green thank you circle. (00:31:50 - 00:32:30)
Continuity mistake: When O'Malley's lawyer arrives in front of the precinct, no protester is left in the street, at least the part behind him - in the following close-up though, in the background a few extras populate the frame. (01:06:05)
Continuity mistake: When Reverend Deke unmasks the guy in blackface, he lowers the hand he had on his shoulder. Return to the close-up: the hand is again present. (01:23:40)
Continuity mistake: When Coffin and Gravedigger go to Lo Boy's hideout and hold him on his feet, multiple continuity errors happen as their hands' position on his arms greatly varies depending on the different angles. (00:33:00 - 00:34:00)
Continuity mistake: Struck by Iris, Mrs. Hill falls to the ground (in obviously sped-up footage, incidentally) face up. As the Rev makes his unceremonious exit, she is lying on one side. (00:39:50)
Continuity mistake: Playing pool with his buddies, Reverend Deke does not hit the cue ball but rather a generic stripe. Moreover, the balls and cotton bit change position between shots. (00:46:30)
Continuity mistake: When the transvestite robs the puny bald street vendor of his coats and furs, absolutely nothing is left on the rack. But in the next shot the poor schmuck has at least a clothing hanger in front of him. (00:13:20)
Continuity mistake: At home with the widow, Reverend O'Malley is talking to her as she stands by the window. The lighting of the scene changes blatantly depending on the angle of the shot - just look at the shadow suddenly in the middle of the curtains in the closer view. (00:29:25)
Continuity mistake: Iris splashes Coffin Ed with the glass as he speak into the phone receiver. She barely gets him and in the same shot as he turns towards the camera to grab her, his jacket and shirt have barely any wet spots. Throughout the scene the stains change in number and size for no reason (even assuming some might have dripped from the cheek to the jacket). (00:17:45 - 00:18:55)
Continuity mistake: When the police catches the pickpocketer at the beginning, they literally lift him off the ground. There is a close-up shot in between, and the lack of continuity is apparent in the hand position of the man. Not just that: vehicles obviously disappear and appear in every cut.
