Olivia Williams has been tapped to co-star on Fox's "Dollhouse."

Joss Whedon's "Dollhouse," from 20th Century Fox TV, revolves around a group of young men and women, aka "Dolls," who are imprinted with different personalities for different assignments. They have no memories of their previous lives, until Echo (Eliza Dushku) begins to try to find out who she was.

Williams ("X-Men: The Last Stand") will play the ruthless and protective Adelle DeWitt who runs the Dollhouse.
