SPOILERS AHEAD FOR AVENGERS ENDGAME!
If you’ve seen Avengers: Endgame by now, you know that Thor (played by Chris Hemsworth), has a drastic new look for the film. Thor is going through a different time, and thus, lets his appearance go.
“He’s broken and that’s who he is moving forward,” Joe Russo, one of the film’s directors, told EW of post-snap Thor. “How is everyone processing their grief? We wanted them all to process it in very different ways. And Thor is an exceedingly tragic character who was built from the time he was a boy to be a king. What is the distance that a character like that can travel, a god? Somebody, especially, who looks like Chris Hemsworth?”
“Even though there’s a lot of fun to be had in the movie with his physical condition, it’s not a gag,” Anthony Russo, the film’s other director, said. “It’s a manifestation of where he is on a character level, and we think it’s one of the most relatable aspects of him. I mean, it’s a very common sort of response to depression and pain.”
“What would happen if that character became extremely angry and started to punish himself and didn’t care anymore?” Joe continued. “What would happen to him? He’s an alcoholic now, he doesn’t care about anything. He doesn’t care about himself.”
“That’s the reason why we didn’t end up turning him back,” Anthony concluded. “It’s an experience that stays with him.”
