The Breakfast Club (1985)
1 revealing mistake - chronological order
Directed by: John Hughes
Starring: Emilio Estevez, Anthony Michael Hall, Judd Nelson, Molly Ringwald, Ally Sheedy, Paul Gleason
Continuity mistake: Claire's hair changes in the library scene. First, it's flat, then she's got it poofed up with a flip on the ends.
Brian Johnson: Dear Mr. Vernon, we accept the fact that we had to sacrifice a whole Saturday in detention for whatever it was we did wrong. But we think you're crazy to make us write an essay telling you who we think we are. You see us as you want to see us - in the simplest terms, in the most convenient definitions. But what we found out is that each one of us is a brain...
Andrew Clark:...and an athlete...
Allison Reynolds:...and a basket case...
Claire Standish:...a princess...
John Bender:...and a criminal...
Brian Johnson: Does that answer your question? Sincerely yours, the Breakfast Club.
Question: Why is it that in the scene where Bender is in the gym, he has a sneaker and boot on, but when he gets back to the library, he has replaced it with his boot? Was there a deleted scene where he loses his shoe or something? It just does not make sense that he would somehow find 1 sneaker, decide to wear it, then kick it off on his way back.





Answer: Bender found the shoe in the gym, and decided to wear it. When the principal kicked the basketball, Bender jumped out of the shoe. He left with his boot, and was wearing it when he arrived at the library.
