In the film, Thor returns to Earth where he meets up again with Jane Foster (Natalie Portman) and don't think she's forgotten that he didn't come see her the last time he was here.
"Thor still has lot of explaining to do, and a lot of making up," says star Chris Hemsworth. "Even demigods end up in the doghouse, mate. So none of us is safe."
To make matters worse, Foster's life is in danger and Thor must bring her back with him to Asgard.
"So while Thor was a fish out of water on Earth in the first two films (Thor and The Avengers), this time Jane is very much a fish out of water in Asgard," says Marvel producer Kevin Feige.
Not only will Thor have to worry about the Dark Elf Malekith, played by Christopher Eccleston, he'll find himself in a love triangle with himself, Jane, and the warrior Sif with his disapproving parents watching.
"It's superhero action, but it's the familiar territory of a love triangle where the parents think your girlfriend is wrong for you," says Feige. "That's how the best of these movies work."
With all that in mind, the film will still have plenty of action and fighting to boot.
"I really wanted to ramp up his skill set in battle," says Hemsworth. "He's not just this Viking throwing the hammer. Here he's more demigod with dynamic moves we haven't seen before."
To further complicate things, Thor must seek the help of his brother Loki, who is still serving time in an Asgard prison.
"Needing Loki's help turns everything on its head," says Hemsworth. "And it allows us to explore the underlying complexities of their relationship. It really ends up being a kind of chess match."
Starring Chris Hemsworth, Natalie Portman, Tom Hiddleston, Stellan Skarsgård, Idris Elba, Adewale Akinnuoye-Agbaje, Kat Dennings, Ray Stevenson, Zachary Levi, Tadanobu Asano and Jaimie Alexander with Rene Russo and Anthony Hopkins as Odin, the film is set for release on November 8, 2013.
