Don't ever let anyone tell you that being a god is easy. Even with all of the superpowers at your disposal, there's still the matter of a cumbersome costume to consider. That's enough to cause discomfort for even the most divine of creatures — like Thor, for instance.
Speaking briefly with Superhero Hype, Hemsworth revealed of his Thor costume: "I put the thing on and said 'It’s not very comfortable, but it looks amazing, so it’s all good.' And then a couple of weeks in, I thought 'It’s getting more and more uncomfortable,' and at the end of three, four months it was a pretty difficult thing to wake up and put on every morning. But it sells such an image in the picture. It does a lot of the work for you."
He's right about that last part, for me at least — the costume works quite well. That's not the only aspect of Thor that's going to work for viewers, in Hemsworth's opinion.
"We just kept trying to humanize it all, and keep it very real. Look into all the research about the comic books that we could, but also bring it back to 'Who is this guy as a person, and what’s his relationship with people in the individual scenes?' And working with someone like Kenneth Branagh, who has all those bases covered and has so many ideas, it was a hell of a time!"
