We saw Hemsworth's Thor in an overweight avatar after the Avengers faced defeat at the hands of Thanos in Avengers: Infinity War. The film saw him living in "New Asgard," with a beer belly. Chris Hemsworth Actually Helped Tom Holland Land The Role Of Spider-Man In MCU! Here's How.

The actor shared a never-before-seen clip of himself in costume on the Endgame set.

Speaking about this video, Chris said, "I didn't even know if I was ever gonna shower, right? 'Cause it was like, in the trailers, in between a few takes... I method-acted the whole [thing]. What else would he be into but 'Hurt' by Johnny Cash? The saddest song in the world."

Even though we thought that Chris did a great job of crooning the saddest song, the actor himself considers that he's "a terrible singer and a terrible guitarist."
