Continuity mistake: In one scene Jim and Amanda run into each other and Amanda gets knocked down onto the pavement. She also drops the coffee, which starts to spill pretty close to here head and almost reaches her hair. In the next shot, both the spilled coffee and the cup are farther away from her head.Christoph Galuschka
Revealing mistake: The blonde model, who is always getting surgery done to change her body, one day has two eye patches on. If you look closely, you can see the eye patches have peep holes, made to look invisible to viewers, but she was falling all over the place and bumping into things and said she couldn't see.
Continuity mistake: As Amanda leaves the party at Jim's apartment, she spots Jim sitting on the stairs. He is not wearing his tuxedo jacket; it is not visible on his lap, over the railing, etc. After the shot switches from the roommates framed in the window back to the couple, Amanda is now wearing Jim's jacket over her shoulders. It is obvious moments later when she returns it to him at his request.
