It's up to Loki to save the world in 1st full trailer for Thor 2

In Thor: The Dark World, desperate times call for desperate measures. This morning we have the film's official trailer that features the return of Chris Hemsworth, Tom Hiddleston, Natalie Portman and Anthony Hopkins.

Like Tony Stark in Iron Man 3, The Dark World finds Thor (Hemsworth) in a different state of mind. He's been traveling across the galaxy fighting evil. But the biggest threat hits close to home when his loved ones are put in danger. Malekith (Christopher Eccleston) has it out for Asgard as well as Thor's lady love, Jane Foster (Portman).

Malekith has a power that Thor's never seen before. He's forced to ask his greatest enemy for help -- Loki (Hiddleston). After causing trouble in both Thor and The Avengers, Loki's locked up in a secure facility. But even he realizes the magnitude of the situation.

"You must be truly desperate to come to me for help," says Loki. That he is.

Is it just us, or is Hiddleston already channelling Eric Draven from The Crow mixed with Snape from Harry Potter?

Thor: The Dark World opens in theaters Nov. 8
