After seeing Orson Welles's "Touch of Evil" at the Expo 58, Truffaut made his feature film directorial debut with "The 400 Blows" (1959), which received considerable critical and commercial acclaim. He won the Best Director award at the 1959 Cannes Film Festival. The film follows the character of Antoine Doinel through his perilous misadventures in school, an unhappy home life and later reform school. The film is highly autobiographical. Both Truffaut and Doinel were only children of loveless marriages; they both committed petty crimes of theft and truancy from the military. Truffaut cast Jean-Pierre Léaud as Doinel. Léaud was seen as an ordinary boy of 14 who auditioned for the role after seeing a flyer, but interviews after the film's release (one is included on the Criterion DVD of the film) reveal Léaud's natural sophistication and an instinctive understanding of acting for the camera. Léaud and Truffaut collaborated on several films over the years. Their most noteworthy collaboration was the continuation of Doinel's story in a series of films called "The Antoine Doinel Cycle".
