6. Cung Le - Pandorum
He's almost an actor first at this point. Cung Le appeared in a short film as early as 2001, but it was really 2009 that saw him break out in the martial arts genre (of film, I mean). That year, he turned up in Pandorum with Dennis Quaid (which is much better than being in anything with Randy Quaid), as well as the feature film Fighting, and something called Bodyguards and Assassins from the Hong Kong film market. He followed that up with a role in 2010's Tekken adaptation, and 2012's The Man with the Iron Fists (which also starred Dave Batista and Russell Crowe, who must have owed someone a favour). Cung hasn't been in anything since, and is preparing for a fight against Michael Bisping in August, but expect to see him back in movies at some point - he's a shoo-in for martial arts action flicks.
