I'm not exactly sure what notes Ron Howard received from the studio following his adaptation of The Da Vinci Code, but I imagine it went something like, "More dead, bloody people hanging in churches!" Indeed, this time around -- for his adaptation of the Da Vinci prequel, Angels & Demons -- there appears to be a lot more ... creepiness. The first couple of teasers and TV spots did nothing to excite the summer movie watcher in me, but I have to say they did a bang-up job with this full-length trailer (watch it below, or in HD over at MSN).

Tom Hanks reprises his role as Dr. Robert Langdon, and he's once again summoned to Rome where he'll need to solve a few puzzles, run around with a beautiful woman and talk a lot about The Illuminati -- all while risking his life, but not dying (because we already know he shows up in the sequel). Perhaps that's not the best description, but I didn't read this particular book -- so head after the jump to get a full, official synopsis. Angels & Demons hits theaters on May 15.
