Charlie Hunnam was known for his role as Jax Teller in the hit FX show "Sons of Anarchy." Hunnman plays another hard core character in his new movie, "King Arthur: Legend of the Sword." At ComicCon, Hunnam talked about his character and said they worked on giving him a rough edge. He explained how they wanted to do a different telling of Arthur, and said: "So he starts off he's tough; he's streetwise; he a little bit selfish but at center of it he has a good heart."
