Bad movie based on an amazing book. Fortunately the title of the books was not used, so the two will never be confused. The books is titled The Club Dumas, and is by Arturo Perez-Reverte. For the movie half the plot (the part referenced in the book's title) was amputated, all depth in the occult plot was widdled away, the female main character (whose name, by the way, is Irene Adler, the name of the woman who defeated Sherlock Holmes) was altered badly, and the ending was badly mangled. As you might be able to guess, I have a bit of a grudge against Roman Polanski for his adaptation of one of my favorite books.
