'The Originals' Bloody Character Posters (Exclusive Photos)

Joseph Morgan as Klaus

Klaus has a lot on his hands when The Originals debuts. "We're used to Klaus coming in with a bull-in-a-china-shop mentality," star Joseph Morgan said at the Television Critics Association summer press tour, "dominating like a one-man army, but Marcel has an army of vampires. He has the numbers. He's running the city and he has the witches under his control. … He's going to have to employ a little bit of his backstabbing methods to get where he wants to be, to take back the throne."
