'Dollhouse' picks up pieces of ended shows

'Battlestar Galactica,' 'Terminator' actors join cast

This fall, "Dollhouse" is going to be a geek-TV haven.

Creator Joss Whedon has tapped actors from Fox's recently canceled "Terminator: The Sarah Connor Chronicles" and Syfy's concluded "Battlestar Galactica" to join the show.

Most notably, he's recruited "Terminator" fan favorite Summer Glau, whom he previously cast in Fox's "Firefly." Glau plays Bennett, a Dollhouse employee who shares a secret past with Eliza Dushku's Echo.

Also, Jamie Bamber (from "Battlestar") will appear as a charismatic businessman who is Echo's new husband. Michael Hogan ("Battlestar" again) comes to Dollhouse hoping to stop a psychotic family member's killing spree. Alexis Denisof ("Angel") is a U.S. senator leading a witch hunt to track down the underground organization. Keith Carradine ("Dexter") is a nemesis of Dollhouse leader Adelle.

Though "Dollhouse" struggled on Friday nights last season, the network hopes the notable guest casting along with some creative tweaks will help the show gain a broader audience.
