The Latest Addition to The Expendables 2 is... Liam Hemsworth?

Variety's Showblitz reports that youngster Liam Hemsworth, who gets his biggest break since dating Miley Cyrus in next year's The Hunger Games, has been cast in the sprawling ensemble of The Expendables 2. Wait, you say -- isn't he, like, four or five decades too young for this film? At 21, Hemsworth is quite a bit less wrinkly than his co-stars. Let's start guessing now who he'll play: Sly's son? A flashback version of Jean-Claude Van Damme? Mickey Rourke's bicep? [Variety]
