Debord began an interest in film early in his life when he lived in Cannes in the late 1940s. Debord recounted that, during his youth, he was allowed to do very little other than attend films. He said that he frequently would leave in the middle of a film screening to go home because films often bored him. Debord joined the Lettrists just as Isidore Isou was producing films and the Lettrists attempted to sabotage Charlie Chaplin's trip to Paris through negative criticism.
