Fresh off a massive summer with The Avengers, Robert Downey Jr.'s Tony Stark will return next April in Iron Man 3 – and if this first trailer is any indication, this is gonna be one doozy of an action movie. It's a different Stark for starters, as the trailer finds our hero without his caustic wit (though fingers crossed that doesn't hold true for the whole film) and instead contemplating the safety of those around him and his ability to protect them as bombs go off and buildings crumble in a taste of the kind of meyhem Ben Kingsley's menacing villain, The Mandarin, will surely bring.
