'Iron Man 3' Trailer: Robert Downey Jr. Stars in Dark New Preview (VIDEO)
Robert Downey Jr. goes to the dark side in the first official trailer for Iron Man 3, released late Monday evening by Marvel.
Devoid of the Iron Man franchise's signature humor, the trailer instead showcases a vulnerable Tony Stark (Downey) as he attempts to pick up the pieces left by The Avengers.
"Nothing's been the same since New York," he says. "I can't sleep. And when I do, I have nightmares."
Even when he's awake, Stark appears to have his fair share of dark times ahead of him.
Among the many: his arch-nemesis Mandarin, who looks to be played to chilling effect by Oscar-winning icon Ben Kingsley.Gwyneth Paltrow), who will hopefully steer Stark from any clear and present danger.
Iron Man 3 -- which reteams Downey with his Kiss Kiss, Bang Bang director Shane Black -- hits theaters in April 2013. Watch the full trailer, above.
