I am so ready to watch movie. I just finished reading the book, and I must say The Da Vinci Code is a page-turner. Whatever controversy surrounds it, on whether it's fiction or not, it doesn't matter. The story is well told, and the author really takes you there. The action and intrigue holds a candle to plots weaved in TV series like 24 and Alias.
If you want to learn something new, or at the very least read about some radical thought (remember, the book is touted as fiction), pick up the Da Vinci Code. Even for just the story. I loved it for the riddles, puzzles, and codes (actually figured out a few).
Info and links pertinent to the movie, the author, the book's references, etc. are compiled on Wikipedia (heed warning on spoilers).
If you're like me, who grew up collecting puzzles (talk about solved jigsaw puzzles piled under the bed because there's no more space to hang them on the walls), you'll try the Da Vinci Code Quest on Google. I'm on the Day 7 puzzle (and kinda stuck! Haha!).
Did you know that the Mona Lisa is both male and female?
