It takes more than CGI and cool costumes to make you look like a literal God.
Chris Hemsworth is a Marvel god, so it's not easy to play that role. You have to work like crazy to gain muscle and bulk, and then lose it.
According to Thor's franchise leader, he doesn't want to work as hard to become the god-muscle.
Hemsworth explains that he has played the same character many times and has put on muscle and gained weight.
He then loses it to play another character. He used to say that it got easier each time.
"This was especially hard." Chris Hemsworth suggested that his physical preparation for Thor's newest movie
was more difficult because Love and Thunder was his highest weight.
