After the events of Avengers: Age of Ultron,[1] and four years after the events of Thor: The Dark World, Thor, held captive on the planet Sakaar without his hammer, must win a gladiatorial duel against an old friend—the Hulk—in order to return to Asgard in time to stop the villainous Hela and the impending Ragnarök, the doom of the Asgardian civilization.
Thor: Ragnarok stars Chris Hemsworth, Tom Hiddleston, Cate Blanchett, Idris Elba, Jeff Goldblum, Tessa Thompson, Karl Urban, Mark Ruffalo, and Anthony Hopkins, and is scheduled to be released on November 3, 2017.
