Chris Hemsworth

It’s National Don’t Flex Day.

A whole new generation of Men in Black will defend our planet from aliens next summer — and the first trailer is here now.

Chris Hemsworth certainly looks the part of a man who’s been stranded at sea; at least 30 pounds lighter than his Thor physique. The shabby clothes hang off him like a kid playing dress up with his parents’ clothes. Don’t get me wrong: behind the beard, the dirt and the sackcloths, Chris Hemsworth is still a pretty handsome dude (it’s almost not fair). I was able to speak with Hemsworth for a few moments about what it was like to build up all that muscle, lose it again, and then have to build it all back up.
