Character mistake: In the scene when Dave is checking out the failed transmitter at the radio station, Dave says "the bad news is your return loss - way too high". This is a mistake, as the movie makers got confused between the terms "return loss" and "insertion loss". Dave should have correctly said either "your return loss - way too low" or "your insertion loss - way too high".
Factual error: At the start of the movie it said "NEW YORK CITY 2000", then went to a panoramic view of New York City minus the Twin Towers. Even though they stated the year was 2000 and they didn't go down until 2001.
Dave Stutler: I don't actually know who you are.
Drake Stone: Really? You don't recognize me?
Dave Stutler: Are you in Depeche Mode?
Trivia: The Rolls Royce Phantom Coupe that Balthazar drives in this movie was owned by Nicolas Cage himself.
