Entertainment Weekly is featuring each cast member of 'The Avengers' providing a brief insight and background information about each.
Here is what EW states about Chris Hemsworth's 'Thor':
"Chris Hemsworth says his hammer-pounding god is not just once again fighting Loki, his villainous brother from Asgard, but also secretly trying to protect him. “I think [Thor's] motivation is much more of a personal one, in the sense that it’s his brother that is stirring things up. Whereas everyone else, it’s some bad guy who they’ve gotta take down. It’s a different approach for me, or for Thor. He’s constantly having to battle the greater good and what he should do vs. … it’s his little brother there,” the actor says. “I’ve been frustrated with my brothers at times, or family, but I’m the only one who is allowed to be angry at them. There’s a bit of that.”
