How big a pop cultural phenomenon is The DaVinci Code? Well, here’s one indication: filming on the movie version of Dan Brown’s runaway bestseller hasn’t even begun (and Westminster Abbey has declined requests for parts of the film to be shot there,) and yet a preview for it is running in front of George Lucas’s latest Star Wars installment. The book has generated considerable controversy amongst Catholics, but the quibbling doesn’t appear to have hurt the book’s popularity, and Hollywood is salivating over the prospect of carving out a chunk of the franchise.
