In a 2017 interview with W Magazine, Chris Hemsworth said that his younger brother, Liam, competed against him for the role of Thor in the Marvel Cinematic Universe.
"I came into the audition with Kenneth Branagh, and thought I nailed it and then never heard anything back," he said. "Months went by and then my brother, my little brother, Liam, was in Australia and sent a tape across and he got a call back, then another call back, and then was down to the last kind of four or five people for it."
While in Vancouver filming "Cabin in the Woods," Chris' manager called Marvel, mentioned that Liam had an older brother, and asked if Chris could audition again.
"So I did an audition in Vancouver in this hotel room with my mum reading Anthony Hopkins' part ... I came in kind of with a little, I guess, motivation and maybe frustration that my little brother had gotten further than me," he said.
It worked out for him in the end because he was cast as the god of thunder.
