In 1972, Debord disbanded the Situationist International after its original members, including Asger Jorn and Raoul Vaneigem, quit or were expelled. (Vaneigem wrote a biting criticism of Debord and the International.) Debord then focused on filmmaking with financial backing from the movie mogul and publisher Gérard Lebovici (éditions Champ Libre), until Lebovici's mysterious death. Debord was suspected of Lebovici's murder. Distraught by the accusations and his friend's death, Debord took his films and writings out of production until after his death. He had agreed to have his films released posthumously at the request of the American researcher, Thomas Y. Levin. Debord's two most recognized films are "Society of the Spectacle" (1973) and "" (1978).
