"Famed stage director Peter Brook -- known for his experimental productions at England's Royal Shakespeare Company -- directed this visceral film of Peter Weiss's fact-based play-within-a-play. While an inmate at France's infamous insane asylum, Charenton, the libertine author the Marquis de Sade (Patrick Magee) directs fellow inmates in a re-creation of the murder of Jean-Paul Marat. Glenda Jackson co-stars."
