'Harold and Maude'

He was a depressed 20-year-old whose hobby was faking suicide in vain bids for his mother's attention. But then he met the world's oldest Manic Pixie Dream Girl and learned to enjoy life and risk heartbreak. Their unlikely romance, 'Harold and Maude,' flopped at the box office when it was released 40 years ago today (on December 20, 1971), yet the movie became one of the most beloved cult hits of all time. Today, there are fans who've seen it dozens of times, yet even they may not know all the bizarre stories behind the film -- from its beginnings as a Hollywood pool cleaner's pipe dream, to how the film's influence extended even to car-design engineers, to star Bud Cort's real-life May-December relationship with an aged Hollywood legend.
