The Ninth Gate (1999)

A thriller directed by Roman Polanski, starring Johnny Depp.
A rare book collector investigates whether a book that a client has is real or a forgery. As he journeys and researches, he finds that each of the 3 copies of the book has 3 of nine original illustrations. Together, they can be used to summon the devil.
The occult ideas implied by this film are interesting, but the film itself is dull. Johnny Depp is meant to play much more interesting roles than this. The plot barely goes anywhere, despite the vast journeys of the main character (who is totally static, by the way). That's enough about this. It gets a bad rating.
