'Thor' Trailer Premieres Online

Marvel's next great superhero lays a smackdown in brand-new clip with a fearsome Chris Hemsworth in title role.

A bearded man in a blue shirt sits silently in a holding room as a man identified as Agent Paul Coulson of S.H.I.E.L.D. interrogates him.

"It's not easy to do what you did," says Coulson, who has apprehended the man only after he disarms several of the official's fellow agents. "You made my men look like a bunch of minimum-wage mall cops. That's hurtful. Would you like to tell me where you received your training? Afghanistan? Chechnya? Who are you?"

With just a single look, the man answers Coulson's question, and that of comic book movie enthusiasts everywhere. The man is Thor, and come May 2011, you'll know his name well.

On Friday (December 10), Marvel Studios and Yahoo! Movies released the first official trailer for "Thor," director Kenneth Branagh's forthcoming adaptation of the classic comic book character's story. Chris Hemsworth stars in the title role alongside an impressive cast that includes Natalie Portman, Anthony Hopkins and Kat Dennings.

In "Thor," our hero hails from Asgard, a faraway, mystical land filled with deadly warriors, powerful sorcerers and other forms of danger. Thor himself is a brave and courageous warrior, but an arrogant one as well. After his reckless behavior reignites an ancient Asgardian feud, Thor is cast out of his homeland by its ruler, his father Odin (Hopkins), and forced to live on Earth to learn a lesson in humility.

But when he lands in mortal territory, Thor gets more than he bargained for in the form of Jane Foster (Portman), a beautiful young scientist with an instant connection to the valiant warrior. Soon, a terrible Asgardian force threatens to destroy Earth, and it's up to Thor to save the day and prevent both of these worlds from utter annihilation.

The official trailer — showcasing much of the same footage that Comic-Con attendees saw over the summer — highlights the film's several action sequences, including a battle between Thor and the Destroyer, an enchanted suit-of-armor hell-bent on destroying the Thunder God. But it's the character work that has our interest piqued: Not only do Portman and the rest of the supporting cast look superb, but Hemsworth positively exudes the godly charm one needs to play Thor.

After seeing this trailer, Robert Downey Jr. might want to watch his back, because Iron Man officially has some competition in the coolest superhero contest!

"Thor" arrives in theaters on May 20, 2011.
