Summer Glau is set to join her "Firefly"/"Serenity" colleague Joss Whedon on the FOX drama "Dollhouse."

Sources at FOX have confirmed for HitFix the news -- first broken via Dollverse -- that Glau will appear in a multi-episode "Dollhouse" arc later this season.

We hear that Glau will play a character named Bennett who shares a past with Eliza Dushku's Echo and has a connection to another Dollhouse character.

Excited yet? How about this for a juicy kernel? We're told that Bennett works for a Dollhouse. Did you notice the key detail there? That would be *a* Dollhouse, not necessarily *the* Dollhouse that we've come to know and love. Then again, it totally could be *the* Dollhouse, but that wouldn't be as fun, now would it?

It's been a poorly kept secret that Whedon wanted to get Glau for a "Dollhouse" role and that he didn't want her to simply play a doll.

Exact specifics on when Glau will first appear (Dollverse says Episode 5) and for how long have yet to be formalized. She joins a growing list of Whedon veterans to drop by "Dollhouse," a group that includes Season One recurring player Amy Acker, season-closing guest star Alan Tudyk and Felicia Day, who appeared in Mysterious 13th Episode "Epitaph One."

Glau was most recently seen on FOX's "Terminator: The Sarah Connor Chronicles," which spent the spring paired with "Dollhouse" on FOX's Sci Fi (not SyFy) Friday. After two seasons of decreasing ratings (but much fan adoration), "Terminator: The Sarah Connor Chronicles" was cancelled in May.

Other credits for Glau include "The 4400," "The Unit" and a cameo as "Summer Glau" on "The Big Bang Theory."


"Dollhouse" will have its second season premiere on FOX on Friday, Sept. 25.
