Chris Hemsworth Debuts “Fat Thor” Singing Johnny Cash On Tonight Show

Chris Hemsworth went to great lengths to transform himself in Avengers: Endgame — complete with a super sad soundtrack!

In the film (spoiler alert!), Hemsworth’s Thor is shown to have grown overweight and despondent in the years following Thanos’ defeat. He lives as a recluse in “New Asgard,” consoling himself and nursing his growing beer belly with alcohol and video games, until Bruce Banner travels to recruit him to try and save the half of the world’s population who got “snapped.”

While fan reactions to “Fat Thor” were mixed, Hemsworth clearly had a blast portraying the new version of his usually-jovial God of Thunder, and on Wednesday’s Tonight Show With Jimmy Fallon, he shared a never-before-seen clip of himself in costume on the Endgame set.
