Plot hole: At the beginning, Bill or his henchman are seen watching the family in the house, which they would have course be doing always. If that is so, then why do they not know about the toy car remote that screws up the video signal in the house?

Directed by: Richard Loncraine
Starring: Harrison Ford, Paul Bettany, Virginia Madsen, Jimmy Bennett, Carly Schroeder
Factual error: When Janet dials 911 from her cell phone, we hear a low tone followed by two higher tones. In reality, 911 is a high tone followed by two lower tones. Additionally, she dials 911 and puts the phone up to her ear without ever pressing the "Talk" button. (01:35:10)
