Thor: Ragnarok (DVD)

Thor is imprisoned on the other side of the universe without his mighty hammer and finds himself in a race against time to get back to Asgard to stop Ragnarok--the destruction of his home-world and the end of Asgardian civilization--at the hands of an all-powerful new threat, the ruthless Hela. But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger--the Incredible Hulk!
