dichen lachman in joss whedon's dollhouse

Fans of Joss Whedon, the creator of popular TV series like Buffy the Vampire Slayer and Firefly, are probably aware of his upcoming return to network television with an original drama series called Dollhouse, starring Eliza Dushku. The show is another sci-fi-themed series about an elite team of secret agents who have "the ability to be imprinted with custom personalities and abilities for special assignments. When they return, their newly acquired memories are wiped." The show follows Dushku's character Echo as she "takes on a variety of assignments—some romantic, some adventurous, some uplifting, some illegal—and gains awareness of her role and confinement."

Okay, sounds interesting enough. According to various websites out there that are already following the production of Dollhouse pretty closely, Dichen Lachman has been cast as Sierra, one of "dolls." According to the casting breakdown, she's described as:

Sierra
20's, Asian or any ethnicity - certainly not Caucasian. Strikingly beautiful. A Doll like Echo, she has every personality in the world but her own. Is not as self-aware as Echo, but is instinctively drawn to her as a friend. Series Regular.

I never got on board the Buffy bandwagon, but I became an admirer of Firefly and Serenity later on DVD. Whedon and Co. have built enough cred to have me at least curious about the universe they create with Dollhouse. I hope it doesn't suck. The show won't be out until the fall, or even mid-season, so I guess I guess we'll have to wait and see.
