Other mistake: In the scene where hundreds of men burst into the place where Penelope Cruz gives her cooking lessons, you can see that one of the waitresses drops the plate she is holding a split-second before the guys swing the doors open and rush past her.
Continuity mistake: In the scene where Cliff arrives at Isabella's place and she wants to have sex with him. When they get to the couch, he loosens his tie. In the close-up shot his tie has been tightened again and then in the shot where they fall to the floor his tie is off altogether.
Monica Jones: Melons are like boyfriends. Shall I tell you why? To get a single good one you must one hundred try.
