Liam Hemsworth - The Things They Say: 3968966
"At the moment he's quite skinny and vulnerable, so I like to take advantage of that for a second. I feel like the older brother. I saw him a couple of weeks ago and this is the skinniest I've ever seen him! It's like, 'I feel somewhat responsible for you 'cause you're just like a child!'"

Chris Hemsworth is currently starving himself for a new role in a film about the true events that inspired author Herman Melville to write Moby DICk.
