The Ninth Gate seems to generate differences of view depending on whether or not you read the underlying novel. I enjoyed both but I would recommend any readers about to become watchers to regard this as a different story from the novel. The film is a strange mixture of fantasy, horror and a thriller. It has a core puzzle to crack (and it's a good one) and lots of good actors acting their socks off. To me its main appeal comes from the anti-hero played by Johnny Depp and the steady pace which Polanski achieves. In each country the story visits it seems to get the local culture just right.
Frank Langella's voice is, once again, dipped in dark chocolate.
