.. which isn't unexpected if you're filming the movie version of Dan Brown's "Angels and Demons". After all, the book's setting in the beginning is at CERN.
They have the same cast as "The Da Vinci Code", i.e. Tom Hanks will return as the same character. But interestingly enough, the "Angels and Demons" book came out first before "The Da Vinci Code". I suppose there isn't anything from one that significantly influence the other in terms of character and story line.
