During his early career as a film critic for the influential magazine "Cahiers du Cinéma", Godard criticized mainstream French cinema's "Tradition of Quality", which emphasized established convention over innovation and experimentation. 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 his 1960 feature "Breathless", helping to establish 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 existential and Marxist philosophy. Since the New Wave, his politics have been much less radical and his recent films are about representation and human conflict from a humanist, and a Marxist perspective.
