7. The production

Calling action for the first time on 9th September 1985, Hughes shot the majority of the movie in and around New Trier High School in Northfield Illinois.

Among the other places shot were various locals in downtown Chicago (including using a float as the Von Steuben Day Parade made its way through the city) and Glenbrook North high school, Hughes' old alma mater.

It wasn't all shot around Illinois - the exteriors of the Bueller family home (which you can see above) were filmed in Long Beach, California.

Those horrified by the destruction of the Ferrari can be assured that, thanks to budget cuts, it's actually a modified MG sports car with a fibreglass shell added.

Three were created for the movie and one really was totaled while the crew shot the ravine crash.

Having got everything he needed in the can, Hughes ended shooting on the movie on 22nd November.

He'd go into the editing room and play around with various sections - adding extra kicks during the scene where Sloane attacks Jeffrey Jones' exasperated Dean Roonie and extending the kiss between her and Ferris as Roonie watches outside the school.

One of the more controversial aspects of the film was the choice of soundtrack. While Paramount originally wanted up-and-coming acts for the movie, the studio eventually dropped the idea in favour of easily-licensed songs.

But despite Hughes' claim that, "I just used what I was listening to at the time, bands I liked. It was my own personal taste," he never agreed to release a soundtrack, worrying that the picked tunes wouldn't work together as one album.

As he locked the cut, Hughes wondered whether he'd have another success.

He needn't have worried...
