Charlie Hunnam [1] has gone through quite the onscreen evolution [2] since his days on Undeclared [3], but this latest role takes his look to a whole new level. He's playing the title role in Guy Ritchie [4]'s upcoming movie, Knights of the Roundtable: King Arthur. Think of the classic Sir Lancelot story, only with more action and hopefully some shirtless Hunnam [5]. He's all covered up in these pictures from the Wales, UK, set, but he does sport a really interesting haircut that we couldn't really see in the first picture from the set [6]. Take a look, and if you can't get enough, you should definitely check out his EW cover [7] and his sexiest Sons of Anarchy moments [8].
