Finally, we've got our first look at "Thor: Ragnarok." In the teaser trailer, we not only get a look at Chris Hemsworth, but also Cate Blanchett, who plays Hela, the Goddess of Death. The minute-and-a-half long clip ends with Thor being pitted against his "friend from work" Hulk, but it's not exactly a loving reunion. "Thor: Ragnarok" hits theaters on November 3rd.
