In 1994,
Claude Chabrol used the screenplay by Clouzot to make his film ''
L'Enfer''. In 2009, Serge Bromberg and Ruxandra Medrea released a 94-minute documentary with material selected from 15 hours (185
reels) of found scenes under the name ''L'Enfer d'Henri-Georges Clouzot''. Bromberg was caught for two hours in a stalled elevator with a woman who turned out to be Clouzot's second wife, Inès de Gonzalez. Upon learning the identity of the woman and of the existence of the footage, Bromberg convinced her to release it to make his film. The documentary includes interviews with nine cast and crew members, notably
Catherine Allégret, the production assistant from 1964,
Costa Gavras, and the assistant cinematographer
William Lubtchansky. Bromberg used the actors
Bérénice Bejo and
Jacques Gamblin to shoot some scenes where dialogue had to be delivered; the found material, which included some 30 hours of
soundtrack, didn't contain suitable material. The film was shown out-of-competition at the
2009 Cannes Film Festival, at the
2009 Toronto International Film Festival, and film festivals in New York, Vancouver, London and Rotterdam; it was nationally released in France on 11 November 2009. In 2010 it received the
César Award for
Best Documentary. ''
