Before it airs tonight during ABC's broadcast premiere of Marvel's Iron Man 2, we have an early look at the extended trailer for Thor: The Dark World, which has just a tiny bit of extra footage from the last trailer we saw, so don't be too disappointed. Alan Taylor directs this Marvel Phase Two sequel, which finds Thor (Chris Hemsworth) teaming up with his nefarious brother Loki (Tom Hiddleston) to stop Malekith the Accursed (Christopher Eccleston) from destroying Earth and the Nine Realms. Natalie Portman, Ray Stevenson, Kat Dennings, Anthony Hopkins, Idris Elba and Zachary Levi co-star in this highly-anticipated adventure, arriving in theaters November 8.
