Chris Hemsworth went through a pretty drastic transformation for Avengers: Endgame. The God of Thunder was severely depressed in the movie and it began to take its toll physically. As a result, he ended up gaining quite a bit of weight and developed a drinking problem in the process. When Marvel Cinematic Universe fans first saw the character, they were blown away. It was a far cry from the body Hemsworth has in real life. And while the prosthetic was impressive, it needed some extra help.

Industrial Light and Magic VFX supervisor Russell Earl led the team who are responsible for the Avengers: Endgame version of Thor. When it comes down to it, getting some extra padding for Chris Hemsworth just wasn't going to cut it. A prosthetic had to be constructed and then Earl brought his team in to finish off the job. He had this to say.

"That was a great prosthetic. He was wearing a prosthetic that I believe Legacy (Effects) did for his suit. There was a big seam down the back that we cleaned up and then we just cleaned it up in places where it didn't quite bend right at the elbows and shoulders. Under the arms, yeah. I think we ended up adding a little bit of hair here and there. I know, it was a great prosthetic, it just required some cleaning up. I think we added some jiggle in a couple of spots too."

Chris Hemsworth had to wear the extra weight during production and even during action scenes. Avengers: Endgame directors, the Russo Brothers, were worried that the actor was going to hurt himself after he started complaining of back pain. Luckily, they were able to get everything done without incident. And thanks to Russell Earl's team, the prosthetic gained some extra weight digitally instead of physically.

Thor's new look in Avengers: Endgame has been divisive amongst certain MCU fans. Some believe the Russo Brothers were being insensitive to people with weight struggles. The directors anticipated this and they insist the weight gain was made to show an accurate depiction of depression. Even the God of Thunder can get taken down by something as powerful as depression, which in turn makes him more relatable.

Avengers: Endgame has many details that MCU fans are just starting to learn about. Marvel Studios did not cut any corners when putting the epic three-hour movie together and it's paying off. The MCU project is currently the second highest grossing movie of all time and it has its sights on taking down James Cameron's Avatar as the highest grossing movie of all time. As of this writing, Endgame sits at $2.62 billion and might not make it to Avatar's $2.78 billion when all is said and done. Maybe some more MCU fans will head back into theaters to dissect Thor's jiggles. The interview with Russell Earl was originally conducted by Comic Book.
