François Roland Truffaut (UK: TROO-foh, TRUU-, US: troo-FOH; French: [fʁɑ̃swa ʁɔlɑ̃ tʁyfo]; 6 February 1932 – 21 October 1984) was a French filmmaker, actor, and critic, widely regarded as one of the founders of the cinematic French New Wave. With a career of more than 25 years, he is an icon of the French film industry.
Truffaut's The 400 Blows (1959) was a defining film of the French New Wave movement, and was followed by four sequels: Antoine et Colette (1962), Stolen Kisses (1968), Bed and Board (1970), and Love on the Run (1979). Truffaut's 1973 film Day for Night earned him critical acclaim and several awards, including the BAFTA Award for Best Film and the Academy Award for Best Foreign Language Film.
His other notable films include Shoot the Piano Player (1960), Jules and Jim (1962), The Soft Skin (1964), The Wild Child (1970), Two English Girls (1971), The Last Metro (1980), and The Woman Next Door (1981). He played one of the main roles in Steven Spielberg's Close Encounters of the Third Kind (1977).
Truffaut wrote the book Hitchcock/Truffaut (1966), based on his interviews with film director Alfred Hitchcock during the 1960s.
He was married from 1957 until 1964 to Madeleine Morgenstern, in 1968 became engaged to leading actress Claude Jade from three of his films, and lived together with Fanny Ardant, actress in his two last films, until his death.
