Maine North High School, located in Des Plaines, Illinois, served as the primary filming location for "The Breakfast Club." Ironically, the school was used for the interior of the high school in "Ferris Bueller's Day Off." However, the exterior for the school in the film was Glenbrook North High.

Alan Ruck's impersonation of Sloane's father was his attempt to make Matthew Broderick crack and break character. The inspiration behind the voice was Broderick's impersonation of their "Biloxi Blues" director Gene Saks. When Saks would get upset and storm off, Broderick would mimic him.

There's a scene in the film in which Neal's wife is lying in bed watching TV. The movie she's watching is coincidentally the John Hughes film "She's Having a Baby," which did not get a theatrical release until February of the following year.

Matthew Broderick and Alan Ruck were close friends before they worked on "Ferris Bueller's Day Off." Though Broderick is six years younger than Ruck, they both played characters of the same age in the Broadway show "Biloxi Blues." So, Ruck's agents convinced the producers of the film to let them both audition.

John Cusack was the original choice for playing bad boy John Bender. He auditioned for the film multiple times before being cast in the role. However, John Hughes stated that Cusack didn't have a threatening demeanor, so he was dropped in favor of Judd Nelson.

The infamous finale scene where Jake Ryan gives Samantha a birthday cake seems romantic, but in reality, that cake is cardboard. Perhaps it was due to budget cuts, or the heat on set, but it's a miracle that it didn't catch on fire.

Ally Sheedy met John Hughes when she auditioned for "Sixteen Candles." At the time, she had two black eyes from a set building accident. When Hughes was considering actors for "The Breakfast Club," he remembered Sheedy's 'gothic look' and brought her in to audition.

When they filmed the school dance in the gymnasium, air conditioning was not allowed due to budget cuts. It got up to 100 degrees on set, making it unbearable to film these scenes. The production experienced the same problem on the set of Sam's bedroom.

John Candy appeared in more movies written or directed by John Hughes than any other actor. Candy appeared in "Uncle Buck," "Planes, Trains and Automobiles," "The Great Outdoors," "Career Opportunities," "Home Alone," "She's Having a Baby" and "National Lampoon’s Vacation."

The name for Lisa came from an early Apple computer. Released in 1983, the 'Apple Lisa' was the first personal computer specifically designed for business users. However, marking it with a price tag of $9,995 didn't help with sales.

A scene from "Uncle Buck" actually inspired John Hughes to write "Home Alone." There's a scene in "Uncle Buck" in which Macaulay Culkin, who plays Miles, interrogates Chanice through a mail slot. Sound familiar?

Elizabeth McGovern starred opposite Kevin Bacon in this Hughes film. Elizabeth is probably more well-known for her time on "Downton Abbey," on which she plays Cora Crawley, the Countess of Grantham.
