It look awesome... getting the Amelie girl to be in it was a perfect move and I just realized Ian McKlellan's in it too. Tom Hanks looks like he can pull it off because he's sort of the kind of guy I thought of when I read about Robert Langdon. By the way, how many cafe-ers have read the book? It's fantastic, although readers should always bear in mind that it's fictitious (although the basic gist of it seems perfectly plausible).
As far as King Kong trailers go... X-Men 3 looks AWESOME!
