By now, it has been established that Marvel has a Cinematic Universe where a lot of characters from the Avengers have their own solo movies with different plotlines. Thor: Ragnarok is going to be that film that will not only discuss what happened to Thor after Avengers: Age of Ultron, but also what happened to Hulk.
One thing that we have reported on before is that the Hulk will have a major role in Thor: Ragnarok. Mark Ruffalo, an Academy Award nominated actor who plays not only Bruce Banner but the big green giant in motion capture has shared about his experience on Thor 3, according to CinemaBlend. He has to put himself in a lot of fake Hulk hands to do the role, not to mention a lot of dots on the face.
So what will the film be about? IGN says that the plotline will be a "mash-up of the Ragnarok story and Planet Hulk". For those who are not familiar with Norse Mythology, Ragnarok is a great battle that precedes the end of the world. In the Marvel comics, it was also the name of clone of Thor that appeared in the Civil War series. Marvel comics also had the Planet Hulk story which showed a world that launched the Hulk off the planet, which caused the Hulk to settle on another world where he could plan his revenge.
There is a lot of story that has been built up in other movies. In Avengers: Age of Ultron, Hulk suddenly went MIA deliberately when it looked like he stole a jet. Even Black Widow's voice couldn't bring him back, and it looked like he had a good romance going on.
Then there are the Thor plotlines. Lest we forget how Thor: The Dark World ended, as it was revealed that Loki (Tom Hiddleston), Thor's half-brother, had apparently taken the throne of Odin (Anthony Hopkins). Considering that Thor thought he was dead, it seems that Loki is playing some kind of long game.
In addition to Chris Hemsworth as Thor and Ruffalo as Hulk, there will be new cast members of Jeff Goldblum, Tessa Thompson, Karl Urban, and Cate Blanchett. It is not known whether or not Natalie Portman's character of Jane Foster will be back, which means that Kat Dennings probably won't be back either.
What is interesting is that Thor: The Dark World really upped the scale of the Thor universe. Asgard was retooled as a cross between Star Wars and The Lord of the Rings, and the scale was a lot more epic than the first film. These Marvel films are starting to be bigger and bigger, and not just the Avengers films. With Asgard and the Hulk in space, it is going to be quite a ride. Viewers will be able to see it for themselves on November 3, 2017.
