17 of 17Sam Worthington
Movie studios keep trying to make Sam Worthington happen. Despite starring in the single biggest film of all time (Avatar) and other action films like Terminator: Salvation and Clash of the Titans, he's still not a household name. Why? Because he doesn't stand out in any way shape or form from the many muscled-up action stars that came before, and the many that will come after. In an age where superheroes like Iron Man and Spider-man can save the world and get a few laughs, Worthington's blandness can't save his impressive, but generic, good looks.
Notable Exception: Avatar (Take a bow, Zoe Saldana!)
