They were five students with nothing in common, faced with spending a Saturday detention together in their high school library. At 7 a.m., they had nothing to say, but by 4 p.m., they had bared their souls to each other and become good friends. To the outside world they were simply the Jock, the Brain, the Criminal, the Princess and the Kook, but to each other, they would always be the Breakfast Club. Emilio Estevez was originally going to play Bender, but Hughes couldn’t find someone to play Andrew Clark so Emilio agreed to play Clark. Anthony Michael Hall’s mother and younger sister play his character Brian’s mother and sister in the movie. The library in which this movie takes place was actually constructed in the gymnasium of Maine North High School specifically for the film. The school closed down in 1982, two years before filming began. The building had been used for park district purposes and the Chicago Blitz before the Illinois state police bought it, turning it into a police station, which it still is to this day. Director John Hughes insisted that the entire cast and crew eat their meals on location in the Maine North High School cafeteria. Share thisThe joke that Bender tells but never finishes (while crawling through the ceiling) actually has no punchline. According to Judd Nelson, he ad-libbed the line. Originally, he was supposed to tell a joke that would end when he came back into the library and said, “Forgot my pencil”, but no one could come up with a joke for that punchline. The license plate on Brian’s mothers’s car is EMC 2. The license plate on Andrew’s fathers’s car is OHIOST. Director John Hughes actually attended Glenbrook North High School, one of the schools where the movie was filmed. The film’s title comes from the nickname invented by students and staff for detention at New Trier High School, the school attended by the son of one of John Hughes’ friends. Thus, those who were sent to detention were designated members of “The Breakfast Club”. “The Breakfast Club” at that school probably took its name in turn from the title of American radio’s longest running network entertainment show, broadcast from Chicago, 1933 to 1968. Most teenage movies that John Hughes has written are also take place in Shermer Illinois and involve a Shermer High School. Weird Science, written by Hughes and also starring Anthony Michael Hall, also takes place in Shermer. Nicolas Cage was originally considered for the role of John Bender but the production couldn’t afford his salary at the time. John Cusack was originally cast as John Bender, but John Hughes decided to replace him with Judd Nelson before shooting began.Director John Hughes said that the cast rehearsed the entire movie as if it was a play a few times before filming began. After the film was a hit, Hughes was asked to write the script as a play so high schoolers could perform it.John Hughes wrote the screenplay to this movie in just two days (4 and 5 July 1982).The theme song, “Don’t You (Forget About Me)”, was written for the film by Keith Forsey. It was a number one hit for Simple Minds, and both Billy Idol and Bryan Ferry turned down offers to record it first (although in 2001, Billy Idol recorded Don’t You (Forget About Me) as a bonus track for his Greatest Hits album).
