Although it doesn't contain any new footage from Thor: The Dark World, Marvel Studios has packaged the best moments from the second trailer into a 60-second TV spot, in case you only have one single minute to spare. Chris Hemsworth returns as the mighty Asgardian, who seeks help from his nefarious brother Loki (Tom Hiddleston) to bring down Malekith the Accursed (Christopher Eccleston) and his army of Dark Elves. Natalie Portman (Jane Foster), Ray Stevenson (Volstagg) and Jaimie Alexander (Sif) are also featured in these scenes from director Alan Taylor's Marvel Phase Two sequel, in theaters November 8.
