One would have to be living under a rock (or high up in the north) for the last five years to claim that they don't know of Game Of Thrones. One of the most loved characters of the HBO mega-hit is Jon Snow, a complicated and deep role brought to life with ease by Kit Harington. He has starred in one lackluster action/disaster film thus far (Pompeii). While the picture may have done damage to his movie career aspirations, like Ryan Reynolds, he was a victim of bad dialogue and a poor plot (everyone dies making the events of the entire movie pointless). With a second chance to prove himself on the silver screen, he can bring a range of emotion and depth to Hal Jordan that several other actors on this list simply can't.
