SAN DIEGO, Calif. -- A cheering crowd here doesn't mean too much -- Gil Gerard would get the same reaction -- but Marvel executives should still be stoked by the response a first look at Iron Man received.

Due next May, it's the first film the comics giant has produced itself. If it bombs, you'll be able to snap up the rights to Thor at Stan Lee's garage sale. That said, the trailer is hugely entertaining -- from Robert Downey Jr.'s arch delivery to scenes of the red-and-gold avenger rocketing through the stratosphere.
