Continuity mistake: Backstage, Deke begins to carve open with a hook the famed bale of cotton. Multiple wads are spread around the main opening. When Coffin Ed throws him on the bale, the smaller bits have vanished. Same happens in a much shorter timespan when he punches him in the gut: clean bale, but multiple wads were scattered a moment before when he threw him on it. (01:26:15 - 01:28:00)
Continuity mistake: At the end, Digger is holding the picture in his right hand, the one he has on the steering wheel, shown in the background. Of course, he never keeps the hand that steady on the wheel in the rest of the scene. And in the last shot of the sequence, as Ed keeps reading, the hand has dropped down already. Also, technically he had the hand on the steering wheel but not holding it, while in the close-up with the animated picture, he is gripping it. (01:35:10)
Continuity mistake: Iris enters the house of the widow with no problem, just turning the knob, and just lets the door close behind her - yet when O'Malley has to escape, people outside the door are frantically trying to open the door to no avail.
Continuity mistake: As the swindling painter tickles/pats the chin of the lady his compadre is snatching the money from, he does that with his thumb outwards or inwards as we switch from shot to reverse shot.
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.
