True Blood

As if True Blood couldn't get any hotter.

On August 30, Evan Rachel Wood joins the HBO hit as Sophie-Anne, the Vampire Queen of Louisiana. She'll make her initial appearance when a desperate Bill seeks out her character for advice.

“Nobody’s ever entirely happy to see her," series creator Alan Ball said of Sophie-Anne. “She’s very powerful, capricious and most likely insane.”

Ball added: “[She] has more than one secret agenda, which we will slowly become aware of over season 3.”
