Marvel has partnered up with YouTube's Geek Week to unveil the second trailer for its upcoming filmThor: The Dark World, a sequel to 2011's Thor and 2012's The Avengers.

In the latest trailer, we see more of both Tom Hiddleston's Loki and Natalie Portman's Jane Foster, as well as further scenes on Earth, in addition to the film's mostly cosmic setting. Though the trailer includes plenty of action and dialogue, little is revealed in the way of plot. The official synopsis is as follows:

"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."

Here's the new trailer for the film:

Thor: The Dark World is scheduled for release on Nov. 8, 2013, and will be screened in both 2D and 3D, as well as IMAX.
