Continuity mistake: During Giselle's first night in New York, from the time she crawls out of a sewer, the bottom of her white gown (and white stockings) becomes somewhat dirty, but by the time she falls asleep on the couch in the apartment, the gown is cleaner.
Continuity mistake: After Pip knocks the apple martini off the table, there is a close-up of him standing on Giselle's plate and the knife is beside the plate with the fork beside the knife. When Robert calls for help, in Pip's next close-up the utensils are placed the opposite way, with the fork beside the plate. (01:00:15)
Continuity mistake: When Giselle stands on the livingroom coffee table as she sings, the hutch stands about a foot away from the fireplace mantle behind her. When she tosses the flowers into the vase, which sits upon the fireplace mantle, the hutch is so close that it nearly touches the mantle.
Continuity mistake: When Robert and Giselle are at Bella Notte's, there is a red checkered tablecloth on the table. The direction of the broad red lines changes between shots, in Chip's close-up when he stands on Gabrielle's plate. First it's horizontal, then vertical - note the knife and fork.
Continuity mistake: At Bella Notte's, after Robert entertains Giselle with the magic trick, the salt shaker is on the table between them and the pepper shaker is at the opposite end of the table, beside Morgan's plate. When Nathaniel brings the apple martini both shakers are beside Morgan's plate, though nobody touched the salt.
Continuity mistake: At Central Park, when Giselle stops at the park bench and hands Clara the money, the tall black lamppost stands a few feet to Clara's left - between her bench and the next bench. When Giselle and Robert walk away, as she says, "And she was very helpful," Clara's bench is much farther away from that lamppost. Also, note the greater distance between Clara and the bench to her left and the park's signpost at the road's curve. (00:44:05)
Continuity mistake: Look at Giselle's right arm when she falls on Robert after stepping out of the shower. In the initial shot, that arm is on the floor. In the next, she's using that arm to hold her towel in place.
Continuity mistake: The argument at Churchill Hairline and Smith LLP office about the Baseball card between the married couple, at the near end of the scene when Ryan is about to leave, the lady says "Let me think" while her hand is resting on her chin. When the camera angle changes her hand is oddly placed on the table. (00:15:25)
Continuity mistake: When Giselle is cleaning her apartment up, flies come down her fireplace in an open flue. Exterior shots of the apartment show no chimney.
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.
Continuity mistake: When Edward stabs the bus, the length of his sword is inconsistent. For it to reach all the way down as far as it did (as seen from inside the bus), it would have to be much longer than it is throughout the rest of the movie.
Chosen answer: Originally she was scripted to have a few scenes with Nancy, Robert's girlfriend, in the design studio. The Producers deleted some of those scenes. You can see that in the DVD under Deleted scenes, where she has a slightly bigger part and actually has a small conversation with Nancy about Robert's text message apology.
