"Me and Natalie Portman and Kat Dennings are doing research on strange atmospheric and space stuff going on in the sky in New Mexico," Skarsgard told Collider of his character. "And then, we meet Thor."
Skarsgard elaborated on his experiences shooting "Thor," pinning much of the film's success on director Kenneth Branagh.
"I had a great time," he said. "Kenneth Branagh is one of the funniest directors on the set. You laugh a lot. He's very skillful. We were also allowed to have rehearsals before we started, and discuss the writing and change the scenes. It felt like you were invited to a very nice collaboration. It's another film done in the real world, where my scenes are."
Despite the fact that he's enjoyed his time working on "Thor," Skarsgard said he hasn't paid much attention to the greater universe that Marvel Studios is establishing with "Iron Man" and other properties.
"That's not the kind of homework I did," he said when asked if he's immersed himself with comic book know-how. "I'm not sure that would have helped. And I was not familiar with Thor at all when I started, but I became familiar. They gave me comic books and stuff, and [Branagh] educated me."
