Thor: The Dark World arrives on Blu-ray (and every other form of home video) next week, but for hardcore Marvel movie fans the hook isn't just getting access to Asgard on-demand, it's the all-new  All Hail the King short the release includes starring Ben Kingsley as The Mandarin/Trevor. In anticipation of the universe-expanding material, Marvel Studios has released one more clip of Kingsley depicting Trevor during his post Iron Man 3 stay in prison. You can check it out after the cut.
