Trivia: In the movie, Reggie comments on Mark's Led Zepplin t-shirt, saying they were a great band. Mark accuses her of being one of those adults who pretends to like cool bands to get close to little punks like him.

Renfro said the same thing to the producer that Mark eventually says to Reggie in the film.

Trivia: The contract in the film stating no film can be made of The Mousetrap until 6 months after the theatrical run ends is actually true in real life as well, albeit only referring to English language versions.
