The Ninth Gate (1999) is a European-production movie, directed by Roman Polanski. It is a neo-noir, mystery thriller about the rare book business, wherein rare-book dealer Dean Corso (Johnny Depp) is hired by bibliophile Boris Balkan (Frank Langella) to validate a seventeenth-century copy of The Nine Gates of the Kingdom of Shadows, by Aristide Torchia, and what he encounters en route.
