The Digital HD release of Doctor Strange, which came out today, offers lots of goodies. But the one that caught most people's eye was the "Marvel Studios Phase 3 Exclusive Look," which includes an early peek at Marvel’s spectacular upcoming films.
During the Thor: Ragnarok segment, concept art was shown of the God of Thunder and The Incredible Hulk fighting in a gladiator arena on planet Sakaar. The Green Goliath is decked out in his Planet Hulk-like armor, featuring a feathered helmet and spiky shoulder armor, and he's shown wielding a massive hammer, sword, and battle-axe.
As for Thor, he's actually wearing his signature helmet, which has been noticeably absent in the Marvel Cinematic Universe.
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 homeworld 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 gladatorial contest that pits him against his former ally and fellow Avenger – The Incredible Hulk!”
Thor: Ragnarok is directed by Taika Waititi, written by Craig Kyle, and returns Chris Hemsworth starring as Thor and Tom Hiddleston reprising his role as Loki. They are joined by Cate Blanchett, Idris Elba, Jeff Goldblum, Tessa Thompson and Karl Urban, with Mark Ruffalo and Anthony Hopkins.
