Les Diaboliques/Trivia

• Enforced Method Acting: For the scene where the staff and students are served spoiled fish, Clouzot reportedly forced the actors to consume the genuine article.
• What Could Have Been: The original film was adapted from the novel Celle qui n'était plus, by Pierre Boileau and Thomas Narcejac. Clouzot supposedly beat out Alfred Hitchcock for the movie rights.
  • Interestingly enough, Hitchcock would obtain the rights to another Boileau/Narcejac novel, D'entre les morts, a couple years later and make it into his film Vertigo.
