With Thor: Ragnarok set to start production this summer in Australia, there have been no shortage of rumors swirling around the project over the past few weeks. A report surfaced last week that the villain of this story is Hela, who may be portrayed by Cate Blanchett. And we also know that Mark Ruffalo is returning as Hulk. Ray Stevenson, who played Volstagg in Thor and Thor: The Dark World, recently revealed in an interview with Geeks Worldwide that he still isn't sure yet if he is returning as this character.

"I'm still in the dark in regards to that, but I'm absolutely blown away to be apart of something that so influential and integral in a part of our generation in regards to movie watching and this Marvel Universe. Its absolutely incredible and if there's a place for Volstagg then great, but right now I don't know. He was great to play. Vikings in space!"

Chris Hemsworth and Tom Hiddleston will return as Thor and Loki, with Mark Ruffalo joining them as Hulk. Both Thor and Hulk are said to go on a "cosmic road trip" in Thor: Ragnarok. It still isn't known if Thor and Thor: The Dark World stars Natalie Portman (Jane Foster), Anthony Hopkins (Odin), Stellan Skarsgård (Dr. Erik Selvig) and Idris Elba (Heimdall) will be back. In a separate interview with Reel Film News, Ray Stevenson reiterated that he isn't sure about his return, teasing how this movie helps build up to the climax in Avengers: Infinity War Part I and Avengers: Infinity War - Part II.

"The Marvel Universe, the way it's played out as you know, has had three Iron Mans, [there will be] three Captain Americas, and then they're building up to this amazing climax of The Avengers. With that said, I feel that everything is geared towards creating a library which fans can immerse themselves in. Now, does this mean that fans will see every single character involved [in Thor: Ragnarok]? Who knows? Would I love to be involved in that? I hope so, however, even if I'm not, I just wish [Marvel Studios] continued success in their incredible endeavor. I definitely feel that [what they have done] has become a staple to our generation. Until you sign the dotted line or know that it's actually a reality, it's up to the powers that be to decide if your character is right for the story. At this point, I don't know."

Thor: Ragnarok will start shooting this summer in Australia, under the direction of Taika Waititi, with Avengers: Infinity War Part I and Avengers: Infinity War - Part II set to shoot back-to-back over a nine-month shoot, starting at the end of 2016.
