Although we've already seen part of this moment in the numerous trailers and TV spots, Marvel Studios has released a new Thor: The Dark World clip that shows Thor (Chris Hemsworth) taking out massive threat Korg the Kronan. Jaimie Alexander's Sif is also featured in this scene that proves the age-old maxim, "The bigger they are, the harder they fall." Watch what might be one of the final clips before director Alan Taylor's Marvel Phase Two sequel hits theaters this Friday, November 8.
