Summer Glau joins 'Dollhouse'

Summer Glau is reuniting with Joss Whedon and joining the cast of "Dollhouse" this fall.

The actress who starred in Fox's now-defunct "Terminator: The Sarah Connor Chronicles" will have a recurring role as Bennett, a Dollhouse employee who shares a secret past with Eliza Dushku's Echo.

The actress previously worked with Whedon on "Firefly." Whedon expressed interest in Glau joining the show back at Comic Con. 

In addition to Glau, Whedon has a whole host of geek-friendly names visiting the show in season two:

Jamie Bamber (from "Battlestar Galactica") is a charismatic businessman who's 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.
