The god of thunder has returned, but this latest adventure doesn't look quite as light-hearted as his first. Making his first post-"Avengers" appearance, Chris Hemsworth is back in "Thor: The Dark World," Marvel's newest tale of Norse mythology, and a new trailer for the film, helmed by "Game of Thrones" director Alan Taylor looks more like a fantasy film than a superhero one.

"Thor: The Dark World" picks up after the events of "Marvel's The Avengers" brought the superhero team together and the New York City to the ground. Now, Thor is back on his home world Asgard, and his adopted brother Loki is imprisoned for his role in the attack.

"Some believe that before the universe, there was nothing," Anthony Hopkins says in the trailer, narrating as Odin, Thor's father. "They're wrong. There was darkness."

That darkness in the movie takes the form of the Dark Elves, a race bent on destruction of the universe. We see some of that terror in this new trailer, as a massive ship crashes into London.

The attack brings Thor back to Earth, where he is once again reunited with his love interest from the first film, Jane Foster, played once again by Academy Award winner Natalie Portman.

From there, Thor and Jane travel back to Asgard to begin a journey that will take them across the nine realms of the cosmos, but they're going to need some help. A big part of the conflict at the heart of "Thor: The Dark World" will be whether the god can trust his ever-mischievous younger brother.

"Thor: The Dark World" opens on November 8.
