Given the question: Suggest a movie title for the following movie plot: Balkan shows his 17th-century copy of The Nine Gates to Corso. Dean Corso (Johnny Depp), a New York City rare book dealer, makes his living conning people into selling him valuable antique books for a low price, and then re-selling them to private collectors. Corso meets with wealthy book collector Boris Balkan (Frank Langella), who has recently acquired a copy of the (fictional) book The Nine Gates of the Kingdom of Shadows by 17th-century author Aristide Torchia, one of only three extant copies. The book is an adaptation of one written by the Devil himself and purportedly contains the means to summon the Devil and acquire invincibility and immortality. Balkan believes two of the copies are forgeries. He hires Corso to check all three, and acquire the legitimate one by any means necessary. Balkan's copy was acquired from Andrew Telfer (Willy Holt), who killed himself soon after. Telfer's widow Liana (Lena Olin) seduces Corso, in a failed attempt to get the book back. Meanwhile, Corso leaves the book for safekeeping with bookseller Bernie Rothstein (James Russo), who is then murdered; his corpse is found posed like an engraving in The Nine Gates. Corso travels to Toledo, Spain. The Ceniza brothers, book restorers, show him that three of the engravings are signed "LCF". Corso deduces that Lucifer himself designed and cut them. Corso travels to Sintra, Portugal, to compare Victor Fargas' (Jack Taylor) copy of the book to Balkan's. To Corso's surprise, he discovers that the signature "LCF" is found in three different engravings, which vary in small but significant details from the images in the Balkan copy. The next morning, a mysterious young woman (identified only as "the Girl") (Emmanuelle Seigner) who appears to have been shadowing Corso since Balkan hired him, awakens Corso and leads him to Fargas' house. He finds the old man murdered and the "LCF"-signed engravings ripped out of that copy. In Paris, Corso visits the Baroness Kessler (Barbara Jefford), who owns the third copy. At first the Baroness refuses...
