Look what I've got - fresh Dollhouse casting prattle! Even better, this performer's name doesn't resemble a word jumble!

English actress Olivia Williams has landed the role of Adelle, the Dollhouse's cold and sophisticated leader. She runs things with an efficiency that is both ruthless and protective. In other words, she would die before she showed anyone how lonely she is.

Never heard of her, but she sure is perty. She's also got a Wikipedia page, which is always helpful. This just in: OMG, she was Bruce Willis' wife in The Sixth Sense! I approve!

Williams joins previously announced Dollhouse residents Eliza Dushku, Tahmoh Penikett, Fran Kranz, Dichen Lachman and Enver Gjokaj.
