"New" and "different" seem to be the two favourite key words being used to describe the upcoming "Thor: Ragnarok." The film is set to be a cosmic adventure involving Thor, Hulk and Loki along with other Marvel characters.

Speaking to E! News about the film, during the premiere of his latest release "Now You See Me 2," actor Mark Ruffalo promised that fans are going to love the new instalment in the franchise.

"I haven't started filming, but I've been prepping for it and I'm really excited about it. I think we're going to do some really cool stuff," the 48-year-old actor said. "We're going to see some new stuff with the Hulk. We're going to see some new stuff with [Bruce] Banner. We're definitely going to see some new stuff for poor old Thor." Ruffalo also added that the film has "got a lot of heart and a lot of fun in it," and he's "excited to get started on that."

Meanwhile, over the last weekend, Thor himself weighed in on what fans can expect from "Ragnarok."

"I think tonally it's a big shift in a great way, more than anything we've seen before," Hemsworth said during a panel at Wizard World in Philadelphia. "There's a, it's a very different Thor, it's a different Loki, I think there's a, we go off on another world that we haven't experienced before," Hemsworth teased.
