Mark Ruffalo spoke with Collider and had the following to say about the upcoming Thor: Ragnarok:
Reiterating that “the only person the Hulk is scared of in the entire world is Banner.”
“What’s exciting about Bruce at this point,” Ruffalo said, “is the arc he’s ultimately making and his relationship to the Hulk. And how that is going to resolve itself. No one’s really gone to that place. They’re coming for a collision course with each other. I think could be pretty exciting if we could find a way to do it, multi-dimensionally.”
How cool is that! Of course they should have just made a Planet Hulk movie and have Thor guest star instead.
