Jean-Luc Godard (UK: /ˈɡɒdɑː/ GOD-ar, US: /ɡoʊˈdɑːr/ goh-DAR; French: [ʒɑ̃ lyk ɡɔdaʁ]; 3 December 1930 – 13 September 2022) was a French and Swiss film director, screenwriter, and film critic. He rose to prominence as a pioneer of the French New Wave film movement of the 1960s, alongside such filmmakers as François Truffaut, Agnès Varda, Éric Rohmer and Jacques Demy. He was arguably the most influential French filmmaker of the post-war era. According to AllMovie, his work "revolutionized the motion picture form" through its experimentation with narrative, continuity, sound, and camerawork.

During his early career as a film critic for Cahiers du Cinéma, Godard criticized mainstream French cinema's "Tradition of Quality" and championed Hollywood directors like Alfred Hitchcock and Howard Hawks. In response, he and like-minded critics began to make their own films, challenging the conventions of traditional Hollywood in addition to French cinema. Godard first received global acclaim for Breathless (1960), a milestone in the New Wave movement. His work makes use of frequent homages and references to film history, and often expressed his political views; he was an avid reader of existentialism and Marxist philosophy, and in 1969 formed the Dziga Vertov Group with other radical filmmakers to promote political works. After the New Wave, his politics were less radical, and his later films came to be about human conflict and artistic representation "from a humanist rather than Marxist perspective." He explained that "As a critic, I thought of myself as a film-maker. Today I still think of myself as a critic, and in a sense I am, more than ever before. Instead of writing criticism, I make a film, but the critical dimension is subsumed."

Godard was married three times, to actresses Anna Karina and Anne Wiazemsky, both of whom starred in several of his films, and later to his longtime partner Anne-Marie Miéville. His collaborations with Karina in Vivre sa vie (1962), Bande à part (1964) and Pierrot le Fou (1965) were called "arguably the most influential body of work in the history of cinema" by Filmmaker magazine. In a 2002 Sight & Sound poll, Godard ranked third in the critics' top ten directors of all time.

He is said to have "generated one of the largest bodies of critical analysis of any filmmaker since the mid-twentieth century." His work has been central to narrative theory and has "challenged both commercial narrative cinema norms and film criticism's vocabulary." In 2010, Godard was awarded an Academy Honorary Award. He was known for his aphorisms, such as "All you need to make a movie is a girl and a gun" and "A film consists of a beginning, a middle and an end, though not necessarily in that order." Some critics have claimed that Godard's films contain prevailing themes of misogyny and sexism towards women. Feminist film theorist Laura Mulvey, has agreed that "While trying to decode a deep-seated, but interesting, misogyny, I came to think that Godard's cinema knows its own entrapment...for feminist curiosity, it is still a goldmine."

Jean-Luc Godard was born on 3 December 1930 in the 7th arrondissement of Paris, the son of Odile (née Monod) and Paul Godard, a Swiss physician. His wealthy parents came from Protestant families of Franco–Swiss descent, and his mother was the daughter of Julien Monod, a founder of the Banque Paribas. She was the great-granddaughter of theologian Adolphe Monod. Other relatives on his mother's side include composer Jacques-Louis Monod, naturalist Théodore Monod and pastor Frédéric Monod. Four years after Jean-Luc's birth, his father moved the family to Switzerland. At the outbreak of the Second World War, Godard was in France, and returned to Switzerland with difficulty. He spent most of the war in Switzerland, although his family made clandestine trips to his grandfather's estate on the French side of Lake Geneva. Godard attended school in Nyon, Switzerland.

Not a frequent film-goer, he attributed his introduction to cinema to a reading of André Malraux's essay Outline of a Psychology of Cinema and the La Revue du cinéma, which was relaunched in 1946. In 1946, he went to study at the Lycée Buffon in Paris and, through family connections, mixed with members of its cultural elite. He lodged with the writer Jean Schlumberger. Having failed his baccalauréat exam in 1948, he returned to Switzerland. He studied in Lausanne and lived with his parents, whose marriage was breaking up. He spent time in Geneva also with a group that included another film fanatic, Roland Tolmatchoff, and the extreme rightist philosopher Jean Parvulesco. His elder sister Rachel encouraged him to paint, which he did, in an abstract style. After time spent at a boarding school in Thonon to prepare for the retest, which he passed, he returned to Paris in 1949. He registered for a certificate in anthropology at the University of Paris (Sorbonne), but did not attend class.

In Paris, in the Latin Quarter just prior to 1950, ciné-clubs (film societies) were gaining prominence. Godard began attending these clubs—the Cinémathèque Française, Ciné-Club du Quartier Latin (CCQL), Work and Culture ciné club, and others—which became his regular haunts. The Cinémathèque was founded by Henri Langlois and Georges Franju in 1936; Work and Culture was a workers' education group for which André Bazin had organized wartime film screenings and discussions and which had become a model for the film clubs that had risen throughout France after the Liberation; CCQL, founded in about 1947 or 1948, was animated and intellectually led by Maurice Schérer. At these clubs he met fellow film enthusiasts including Claude Chabrol and François Truffaut. Godard was part of a generation for whom cinema took on a special importance. He said: "In the 1950s cinema was as important as bread—but it isn't the case anymore. We thought cinema would assert itself as an instrument of knowledge, a microscope... a telescope.... At the Cinémathèque I discovered a world which nobody had spoken to me about. They'd told us about Goethe, but not Dreyer. ... We watched silent films in the era of talkies. We dreamed about film. We were like Christians in the catacombs."

His foray into films began in the field of criticism. Along with Maurice Schérer (writing under the to-be-famous pseudonym Éric Rohmer) and Jacques Rivette, he founded the short-lived film journal La Gazette du cinéma [fr], which saw the publication of five issues in 1950. When Bazin co-founded the influential critical magazine Cahiers du Cinéma in 1951 (a seminal publication on cinema and its main observers and participants), Godard was the first of the younger critics from the CCQL/Cinémathèque group to be published. The January 1952 issue featured his review of an American melodrama directed by Rudolph Maté, No Sad Songs for Me. His "Defence and Illustration of Classical Découpage" published in September 1952, in which he attacks an earlier article by Bazin and defends the use of the shot–reverse shot technique, is one of his earliest important contributions to cinema criticism. Praising Otto Preminger and "the greatest American artist—Howard Hawks", Godard raises their harsh melodramas above the more "formalistic and overtly artful films of Welles, De Sica, and Wyler which Bazin endorsed". At this point Godard's activities did not include making films. Rather, he watched films, and wrote about them, and helped others make films, notably Rohmer, with whom he worked on Présentation ou Charlotte et son steak.
