Uh-oh. It seems a stuntman working on Thor: The Dark World may have accidentally given away who the bad guys are in the new film.
In an interview with I Review Too, stuntman James Grogan let this little bit slip out:
The other day for example, this is quite random but I was working on Thor 2,” he explains, “I had a load of stunt guys in and the director came in and he said ‘Look, we want you all to be elves,’ and I was like ‘What the hell is an elf anyway?’ and he said ‘I want you all to walk around like these supernatural animals,’ honestly it was the most ridiculous thing ever but you just have to not be self aware and get on with it.”
It appears that the “Dark World” referred to in the title will be Svartalfheim, home of the Dark Elves.
Svartalfheim is known as the seventh world of Asgard. It exists on an extradimensional plane that consists of major land masses which can be reached via nexus portals that exist on each of these worlds except for Midgard, and some of these worlds are in direct contact with the roots of Yggdrasil, the cosmic ash tree that stands in Asgard.
