Continuity mistake: At Katz's deli, when Pip stands on the cup scooping up the ice cube, the fork on the tray is to the right of the blue ticket. When Pip stands on the tray the ticket has moved to the tray's edge, and the fork is now to the ticket's left. (00:39:45)
Continuity mistake: When Nathaniel leaves the hotel room after he hangs Pip in the closet, there is a window shot of him crossing the street and heading to a snow covered sidewalk the next day. But when Pip frees himself and runs outside, there is no snow.
