UPDATE: So apparently this is not Blake, just some random dude named Richard that Jane has a date with. Why O'Dowd was so secretive about that in interviews I have no idea, but at least we got some fun speculation out of it!
Marvel Studios’ “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.
Thor: The Dark World stars Chris Hemsworth, Natalie Portman, Tom Hiddleston, Stellan Skarsgård, Idris Elba, Christopher Eccleston, Adewale Akinnuoye-Agbaje, Kat Dennings, Ray Stevenson, Zachary Levi, Tadanobu Asano and Jaimie Alexander with Rene Russo & Anthony Hopkins. The sequel hits theaters November 8, 2013.
