If those set photos from the Bourne Wood set of Thor: The Dark World whet your appetite for more Asgardian action, then you're in luck: Splash News has released video of stars Chris Hemsworth and Jaimie Alexander battling still-unidentified foes. The voiceover is pretty terrible, so you may want to watch with the sound off.
Although the Surrey location was widely assumed to double for Svartalfheim, it's unclear from the photos and video whether Thor and Sif are battling Dark Elves or another race. Marvel Studios President Kevin Feige teased last year that the sequel will “take Thor literally to other worlds," so it's possible we'll see several regions of the Asgardian dimension (for instance, it's been reported that Iceland may serve as a shooting location, suggesting a stop in Jotunheim, home of the Frost Giants).
Directed by Alan Taylor (Game of Thrones), Thor: The Dark World also stars Tom Hiddleston, Natalie Portman, Kat Dennings, Anthony Hopkins, Idris Elba, Zachary Levi, Adewale Akinnuoye-Agbaje and, potentially, former Doctor Who star Christopher Eccleston. The film opens Nov. 8, 2013.
