Ferris Bueller's Day Off is 30 years old this year.

This weekend fans of the movie will be flocking to Ferris Fest, a special event taking place in Chicago featuring screenings of the film, a Q&A with its stars, a tour of all the filming locations, and a live recreation of the film's 'Twist and Shout' parade sequence.

To celebrate the occasion, here's a selection of trivia about the film described by the Telegraph's Mark Monahan as the "best film writer-director John Hughes has ever made: a pin-sharp, exquisitely funny and occasionally profound portrait of the perennial struggle between youngsters (good) and adults (clueless at best), very much of its time but still fresh as a daisy."
