Yahoo! Movies has debuted a featurette for Thor: The Dark World that brings viewers up to speed on the complex relationship between Chris Hemsworth's god of thunder and Tom Hiddleston's Loki, and establishing their uneasy alliance in the upcoming Marvel sequel.

"Suddenly Thor and Loki are bound together on the same journey, with the same goal, but completely different ways of going about it," Hiddleston explains, referring to their mission to stop Malekith from plunging the Nine Realms back into darkness. "This film is beyond any of my expectations. It's amazing."

"There's an epic feel to it," Hemsworth adds. "It's hugely exciting."

Directed by Alan Taylor, Thor: The Dark World also stars Natalie Portman, Stellan Skarsgard, Idris Elba, Christopher Eccleston, Adewale Akinnuoye-Agbaje, Kat Dennings, Ray Stevenson, Zachary Levi, Tadanobu Asano and Jaimie Alexander with Rene Russo and Anthony Hopkins. It opens everywhere Nov. 8.

Marvel’s Thor: The Dark World continues the big-screen adventures of Thor, the mighty Avenger, as he battles to save Earth and all the nine realms from a shadowy enemy that predates the universe itself. In the aftermath of Marvel’s Thor and Marvel’s The Avengers, Thor fights to restore order across the cosmos … but an ancient race, led by the vengeful Malekith, returns to plunge the universe back into darkness. Faced with an enemy that even Odin and Asgard cannot withstand, Thor must embark on his most perilous and personal journey yet, one that will reunite him with Jane Foster and force him to sacrifice everything to save us all.
