obviously i can't keep reposting the same links of the same sites all the time when ever they have a new update about casting but it is nice to keep up with the latest news

here's the main characters that have been released from joss's script so far

Adelle DeWitt
40 something, any ethnicity, beautiful, sophisticated, cold as an alp. Runs the Dollhouse with an efficiency that is both ruthless and protective. Would die before she showed anyone how lonely she is. Series Regular ;

Paul Smith
30s, any ethnicity, good-looks hardened by a cynical distaste for most of humanity. An FBI field agent, he’s been chasing the urban myth of the "Dollhouse" long enough to have lost any shot at promotion. Becomes obsessed with, and twisted romantic foil for, Echo. Series Regular ;

Boyd Langton
Late 40s-60, any ethnicity, gruff, about to make the descent from ’good-looking’ to ’fatherly’. An ex-cop, Boyd is Echo’s ’handler’ - her guard/bodyguard. Hates himself for taking this job, bu he’d lay down his life to protect the people he feels he’s exploiting. Series Regular ;

Topher Brink
20’s, any ethnicity, genius programmer who’s articulate, nerdily attractive and blithely amoral. He’s responsible for imprinting the dolls - and making sure they stay unaware of anything. Is fascinated by the science and kind of digging the illegality. Fun to be around, but might not be remotely trustworthy. Series Regular ;

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 ;

Victor
20’s, any ethnicity, handsome and fit. A Doll, and the other closest thing to a friend Echo has. Childlike when he’s inactive, and everything from Errol Flynn to (young) DeNiro when he’s active. Series Regular ;

November
20’s, any ethnicity, beautiful and heavy. Another Doll, a hopeful child in the house and everyone else you need her to be outside. A comforting, radiant presence, who tends to get fewer of the criminal gigs and more of the personal ones. Recurring ;

Dr. Claire Saunders
30-60, attractive, smart and a little sad. Looks after the physical well-being of the dolls. Has an acid wit that she usually reserves for Topher, who may only be kidding about being smitten with her. (Or he may not). Recurring.
