Fate favors some films. A stalled elevator threw together noted film restorer Serge Bromberg and Inès Clouzot, widow of director Henri-Georges Clouzot. In the course of two stranded hours, a discussion of Clouzot’s unfinished film, Inferno, inevitably arose. Subsequently, Inés Clouzot agreed to give Bromberg access to the surviving 13 hours of film. This stunning footage becomes the backbone of the resulting documentary, which offers a fascinating, partial reconstruction of Inferno while chronicling the production’s disintegration.
