'Iron Man 3' Trailer Shows a Tense Tony Stark (Video)

Robert Downey Jr. returns as billionaire genius Tony Stark, this time going up against The Mandarin.

In a new trailer for Iron Man 3, it looks like the "genius, billionaire, playboy, philanthropist" Tony Stark (Robert Downey Jr.) has the weight of the world on his shoulders this time.

The third installment in the superhero franchise sees Stark gearing up to go up against his greatest foe, The Mandarin (Sir Ben Kingsley), after he blows up Stark's Malibu home, shaking Stark's world.

Stark’s signature bravado seems to have been shaken by the attack on his home, plaguing him with concern about the safety of his lady-friend Pepper Potts (Gwyneth Paltrow).

The film, which reunites Downey Jr. with his Kiss Kiss Bang Bang director Shane Black, will test the brash-but-brilliant industrialist with the question that’s always haunted him: Does the man make the suit or does the suit make the man?
