"Iron Man 3" trailer is here, and Tony Stark means business

Things are different for Tony Stark now. He's in love. He's out for revenge. And apparently he can't sleep.

The action-packed trailer begins with a grim voice-over from Robert Downey Jr. saying: "I'm Tony Stark: I build neat stuff, I got a great girl, and occasionally save the world. So why can't I sleep?"

So if that's any indication of the direction of "Iron Man 3," it looks like things are going to be a little less fun for Tony Stark, and possibly for viewers. In this third installment -- due in theaters May 3 -- Tony says, "No politics here. Just good ol' fashioned revenge."

And that revenge is presumably aimed at bad guy The Mandarin (a ponytail-clad Ben Kingsley). Over shots of mayhem, explosions, and a struggling Gwyneth Paltrow, Kingsley utters evil lines like, "Today is the first day of what's rest of your life" and "Do you want an empty life or a meaningful death?" Meanwhile, Guy Pearce puts the fate of the world in Tony's hands.

So yeah, Iron Man's got a reason or two to pop an Ambien.

But don't worry, it's not all sad faces for "Iron Man." There are still some signature funny quips and one-liners between Downey and Don Cheadle, and the special effects are amazing as always.
