The trailer for 'Thor' has finally hammered itself straight into the public's Marvel obsession (watch it after the jump). Due out on May 6th, it could be said that 'Thor' is this year's 'Iron Man' -- a launching pad for a new Marvel character that we're familiar with from the comics and cartoons (and 'Adventures in Babysitting'), but not completely sold on yet. This is the first big-budgeted live-action film for Thor, and at first it seemed like somewhat of a risky move putting a director like Kenneth Branagh in the driver's seat, though now the decision makes complete sense.
