First 'Iron Man 3' Trailer Reveals Darker Take on the Marvel Hero (Video)

Robert Downey Jr.'s Tony Stark is moody and Ben Kingsley's Mandarin is creepy in the preview for the 'Avengers' followup.

How do you follow up a $1.5 billion blockbuster like The Avengers? If you’re Marvel Studios, you make it personal.

It's apparent that Tony Stark (Robert Downey Jr.) is still reeling from the events of The Avengers in the first trailer for Iron Man 3.

"Nothing's been the same since New York," he says. "I can't sleep. And when I do, I have nightmares."

It appears his creations turn on him, as we get a shot of an Iron Man suit sneaking up on Stark in his sleep. We also get a terrifying taste of what Ben Kingsley's performance as Iron Man arch-nemesis Mandarin will be like, with the character giving a creepy voice over.

"Some people call me a terrorist. I consider myself a teacher," he says. "Lesson number one: Heroes: there is no such thing."

The project reunites Downey with Gwyneth Paltrow (Pepper Pots) and Don Cheadle (James Rhodes/War Machine).
