Iron Man's not the only Avenger who's coming back to cinemas this year — Thor (Chris Hemsworth) returns to the big screen in October, and he's got quite a lot on his plate. His first priority is coming back to Earth for Jane (Natalie Portman), his girlfriend, whom he plucks out of London right in the middle of a science experiment. Odin isn't exactly safe for a human, though, because there's a new bad guy in town named Malekith who has an entire army of Dark Elves. So whom does Thor turn to? Why, his deranged brother, Loki (Tom Hiddleston), who is now locked up (and hasn't seemed to have washed his hair).
I loved the lighter, sillier tone of the original Thor movie (compared to, say, Captain America), but the trailer isn't exactly packed with jokes — though I guess that's to be expected when the word "dark" is right there in the title. Still, I'm looking forward to seeing what develops in Thor's action-packed next chapter come Oct. 31. Watch the trailer after the jump.
