A highly intense and prolific actor with a penchant for iron-willed roles, Denis O'Hare emerged as one of the most memorable characters on "True Blood" (HBO, 2008-14), playing the chief antagonist, the Vampire King of Mississippi, during the show's third season. An accomplished stage actor, O'Hare made a career portraying various authority figures - a priest on "Law & Order" (NBC, 1990-2010), a brusque immigration officer in the comedy "The Proposal" (2009), and a rigid state senator in the biopic "Milk" (2008). But his career reached a pop culture high when he joined the cast of "True Blood," director Alan Ball's popular fantasy saga. As the vampire king, O'Hare manifested true evil, yet he brought a surprising levity to the role by expressing delight in the supernatural, even when going against him. O'Hare successfully brought to life a character that was on the exterior a polite Southern gentleman, but was also the true incarnation of evil; successfully essaying this dichotomy proved the actor's immense talent was no fluke.
