Ferris Bueller's Day Off

John Cusack, Jim Carrey, Johnny Depp, Tom Cruise, Robert Downey Jr. and Michael J. Fox were all considered for the role of Ferris Bueller.

Alan Ruck was 29 years-old when he played the role of Cameron.

The John Lennon quote Ferris speaks early in the film, "I don't believe in Beatles, I just believe in me" is from Lennon's song God. It can be found on his 1970 album, Plastic Ono Band.

To produce the desired drugged-out effect for his role as the drug addict in the police station, Charlie Sheen stayed awake for more than 48 hours before the scene was shot.
