Factual error: This movie is set in New York. In the beginning of the movie, Ryan (Charlie Sheen) is working as a stock broker and is at work in a high rise office building. Library Tower is clearly visible through the window. This is the tallest building in California. Imagine if the Empire State Building was visible in a movie set in LA. (00:10:50)
Continuity mistake: When Ryan is talking to Page in her office about Cindy's medical condition she hands him a white coffee mug with black stripes. In a close-up, the mug has changed to a white one with a square picture on one side (the one Page took). It subsequently changes back again. (00:25:40)
Continuity mistake: As Ryan is leaving Page's office after telling her about Cindy's condition he is holding the coffee mug she gave him. When we see him in the next shot he is no longer holding the mug. (00:26:20)
Continuity mistake: When Ryan is talking with Page over drinks/contract discussions, the camera moves in and out from Ryan/Page to Page. In the switch between close-up and distant shots, you see locks of hair dangling near Page's face in the close-ups, but, in the distant shots, her hair is perfectly set. (00:52:30)
Audio problem: When Cathy gets a telephone call in her yoga class we hear a Nokia tone, but she has got a Motorola telephone in her hand. (00:37:45)
Continuity mistake: When Page and Ryan chase after Cindy (after she threatens to go to the networks) Ryan's hair is messed up and his shoes are untied. When he and Paige get to the street Ryan's hair is combed and his shoes are tied. (01:16:00)
