"True Blood star Denis O'Hare has confirmed that he will return to the show.
The actor, who appeared in the HBO drama's third season as vampire king Russell Edgington, recently announced that he will reprise his role in a potential fifth run.
O'Hare told Film School Rejects: "It was up in the air. They were definitely bringing me back, it was just a matter of if they wanted to bring me back the last couple episodes [of season four] or bring me back at the beginning [of season five]. So they decided to do it at the beginning of season five."
O'Hare, who recently signed up for FX pilot American Horror Story, added that there will be "no limit" to Russell's actions in future episodes of True Blood.
"Obviously characters evolve, and part of the reason [Russell] evolved was they kept making him older and older," he explained. "We made him this Pagan Celt [and] they are just wild people.
"They have a very different relationship to everything in terms of nature and in terms of their own belief system. I just love that."
