When Amanda moves into the apartment, Jade, Roxanna, Holly and Candi run up to her to convince her to lend Jade her top. All four models are topless, but by the time that they get to the front door, they all have their tops on, and their new tops are different from the ones they were trying on before.
When the Russian man with the beard visits the models' apartment, a girl answers the door with a book on her head. As she talks, it begins to slide to the left of her head, the camera angle then changes to a view over her left shoulder, her arm never moves, but in the next shot the book is perfectly balanced atop the center of her head.
Jim Winston demonstrates his dagger-throwing prowess by throwing a dagger at a room divider. The dagger hits the divider several feet above the release point, and at least six or seven feet to Jim's left. It should have struck the wood angled significantly down and to the right. In the close-up, however, the dagger is shown stuck in the wood with its axis perfectly level, and at 90 degrees to the surface.
