Nobody understands sibling rivalry more than Thor, but by extension, the same goes for the actor who plays him, Chris Hemsworth. Though he definitely wasn't dealing with someone like Loki, it turns out that Hemsworth dealt with some significant sibling rivalry with his younger brother Liam, which ultimately helped him land the role of Marvel's Asgardian God of Thunder.

Thor: Ragnarok is the third film within the Thor series (as well as Hemsworth's fifth feature film starring as the character), but his place within the Marvel Cinematic Universe wasn't always a safe bet.

In fact, his first audition seemed to be a bust, according to what Hemsworth said in an interview with W Magazine, and he almost lost the part to his younger brother, Liam (who ended up landing his own franchise with The Hunger Games alongside Jennifer Lawrence). According to the interview, he said:

“I came into the audition with Kenneth Branagh and thought I nailed it and then never heard anything back. 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. I remember sitting in Vancouver, shooting Cabin in the Woods with Drew Goddard and Joss Whedon. Both of them were looking at the trades at this sort of top five guys for Thor and saying, ‘Why aren’t you in the mix here? What happened?’ I said, ‘I don’t know. I blew my audition I guess.’"

It turns out that none of the "top guys" who were being considered were offered the role, which essentially left the door wide open, much to his luck. He added:

"I came in kind of with a little, I guess, motivation and maybe frustration that my little brother had gotten further than me. It's a little family, sibling rivalry sort of kicked up in me. Then it moved pretty quick from there. It was cool."

After working together on Cabin in the Woods with the film's writer/producer Whedon - and following Whedon's curiosity as to why someone of Hemsworth's stature and talent wouldn't be considered for the role - their connection ended up becoming almost serendipitous. Two years after filming Cabin, Whedon was brought on to direct The Avengers, pairing up the actor and director for a second time.

As for the relationship between brothers Chris and Liam, everything appears to be just fine.
