Continuity mistake: In the scene where Billy Crystal and Robert De Niro are eating at a Sushi Bar with a crew of people, Billy Crystal is acting up due to a reaction of medication and alcohol. Robert De Niro threatens Billy by telling him that he would stick a f***ing fork in his eye; when De Niro is waving the fork around you can plainly see a noodle on Billy Crystal's face, however, when the shot changes a second later, and shows Billy Crystal and Robert De Niro, there is nothing on Billy Crystal's face; the noodle has disappeared.
