There’s another lovely interview with Mr. Whedon about Dollhouse; below is a snippet about Amy’s character — it sounds like a fantastic role! — and you can read the article in full at IGN (opens in a new window.)
Question: Can you talk about Amy Acker’s character?
Whedon: Amy plays Dr. Claire Saunders. She works in the Dollhouse and she’s a very moral force and she’s very, very, very broken. She’s scarred. Something happened – she’s literally scarred. Something happened at the dollhouse awhile back and she was scarred and she just sort of lives there and her whole mission in life is to take care of them. Topher, the programmer, he programs them and has a very amoral kind of point of view, and she’s sort of his counterpoint.
