The 400 Blows (French: Les Quatre Cents Coups) is a 1959 French New Wave drama film, and the directorial debut of François Truffaut. The film, shot in DyaliScope, stars Jean-Pierre Léaud, Albert Rémy, and Claire Maurier. One of the defining films of the French New Wave, it displays many of the characteristic traits of the movement. Written by Truffaut and Marcel Moussy, the film is about Antoine Doinel, a misunderstood adolescent in Paris who struggles with his parents and teachers due to his rebellious behavior. Filmed on location in Paris and Honfleur, it is the first in a series of five films in which Léaud plays the semi-autobiographical character.
