Actors Who Went Through Extreme Transformations For Roles

Chris Hemsworth, Thor

He may look the part today, but Ozzie native Chris Hemsworth had to build some serious muscle before playing Thor in the Marvel Cinematic Universe. In 2010, he had private gym sessions with former Navy Seal Duffy Gaver. Special emphasis was placed on building Hemsworth’s arms and chest – giving him that superhero pop.

Overall, he gained 20 pounds of muscle and has kept it going way until 2019’s Avengers: Endgame. It’s unclear where Thor will go after this summer.
