After starring in the Jerry Bruckheimer movie "Pirates of the Caribbean: The Curse of the Black Pearl," Keira Knightley reteams with the producer for a new version of the classic tale, "King Arthur." According to SciFi.com, Knightley expects this "Arthur" to be bloodier than previous incarnations, indicating that it'll be more along the lines of "Gladiator" than "Excalibur."
