Natalie Portman has a lot to look forward to in Kenneth Branagh's "Thor" film, which she's scheduled to begin production on soon as Jane Foster. Anthony Hopkins, Idris Elba and Chris Hemsworth are all confirmed to be starring at her side, but Portman dropped a potential casting bombshell this weekend while promoting her new film "Brothers." "Nick and Norah's Infinite Playlist" star Kat Dennings may have a role in "Thor" as well.

"Well I'm really excited," Portman told MTV News. "Kat Dennings is going to be in it with me and she's a good friend and an amazing actress, so I'm looking forward to that."

The "Thor" cast is already full of big names, and most of the obvious characters from the comics have already been cast, but Kat Dennings' arrival would still be huge news -- though it raises a sizable question mark over who she might be playing.

Portman seemed enthusiastic about her own part and the world of Asgard that Branagh will be adapting to film.

"Well, I was really excited when they told me Kenneth Branagh is directing it because it seemed like such a smart choice but such an unexpected choice, that it was like 'This is really weird. I have to try this,'" Portman said.

Arriving in the Marvel Universe's rendition of Norse mythology has required a lot of education, but she's currently hard at work figuring out how it's put together. "Yeah I've been learning more about it now," she explained. "I was really unschooled about the world of Thor before."

Dennings previously said that she'd like a shot at Tim Seeley's "Hack/Slash," but she made no mention of "Thor." There aren't many big female parts left in Asgard, but Dennings definitely has the moxie to pick up the part of Enchantress if she happens to be in the script. That's just a hunch, mind you, but the floodgates of speculation are now unofficially open.
