Truffaut's The 400 Blows is considered by many to be the first film of the French New Wave, and somewhat autobiographical, and Truffaut has been quoted as saying that the film saved his life.
It has been suggested that there are quite a few similarities between Antoine Doinel and Holden Caulfield (Protagonist of The Catcher in the Rye), i.e. they lurch from adventure to adventure, both feature somewhat displaced, rebellious teenage boys, placed in a major city, and both feature main characters that are not really a part of any group, and tend to get excluded or shoved out of groups.
Is there any evidence that Truffaut was influenced by J.D. Salinger (Catcher in the Rye, 1951) when penning the screenplay for 400 Blows (released 1959), or is it more a desire to rattle the cages of the Cannes judges who had banned Truffaut the year before?
