Cast approval

The Da Vinci Code movie has a lead cast... and it looks mighty fine to me.

Tom Hanks as Robert Langdon? Sure, why not? He's only one of the best actors in the business. There's little doubt there as to whether he can carry a movie.
Audrey Tautou as Sophie Neveu? Never heard of her, but her looks guarantee she'll do the job.
(Sir?) Ian McKellen as Leigh Teabing? A fine actor, I must say, and he's definitely got enough British aristocracy in him to get the point across.
Alfred Molina as Bishop Aringarosa? I had to look this guy up on IMDB before I recognized him, but I think he'll do a good job with this role. Even though one of his last credits was playing Doctor Octopus in Spiderman 2, I think he could pass off as a conservative Spanish bishop anyday.
Jean Reno as Bezu Fache? YES! I have to say that I jumped for joy after seeing this credit. He's the perfect man for this role: a badass Frenchman who has redefined the meaning of "five o'clock shadow."
Paul Bettany as Silas? Well for one thing, he is definitely white enough for the role of an albino. But that aside, I think he can muster enough Opus Dei angst in him to play an effective antagonist.

Overall, I say props to the casting director. This should be a hell of a movie.
