Looks pretty cool to me as a movie, tho' Brown's grasp of semiotic knowledge in the book ruined it for me. Maybe he should have enrolled at Bologna under Eco prior to writing the book, before making the lead character a semiotics professor. I did notice a strange combination of letters in the trailer, I'm rubbish at crosswords/anagrams, maybe somebody else is better, could be a secret message

The only thing that I could get from it was 'The Decos' which makes me think of a ten part encryption...but hey maybe I'm looking too deeply...or maybe its because I have 'Applied Cryptology' by Bruce Scheiner on my desk
Under the Rose, weren't there two encryption wheels??? One within another, 5 + 5 = 10, and thus 'The Decos'. That's all I can think of.
