In Paris, in the beginning of the Twentieth Century, Cesar Charron owns a theater at the Rue Morgue where he performs the play "Murders in the Rue Morgue" with his wife Madeleine Charron, who has dreadful nightmares. When there are several murders by acid of people connected to Cesar, the prime suspect of Inspector Vidocq would be Cesar's former partner Rene Marot. But Marot murdered Madeleine's mother many years ago and committed suicide immediately after.
Murders in the Rue Morgue is a 1971 American mystery horror film directed by Gordon Hessler by American International Pictures (AIP). It stars Jason Robards, Christine Kaufmann, Herbert Lom, Adolfo Celi, Michael Dunn and Lilli Palmer. The screenplay by Christopher Wicking and Henry Slesar is a loose adaptation of Edgar Allan Poe's 1841 short story of the same name. However, it departs from Poe's version in several significant aspects, at times more resembling Gaston Leroux's The Phantom of the Opera, and incorporating the historical character Eugène François Vidocq.
