Thanks to Helena World we have a transcript of an interview with Helena Bonham Carter from the Sweeney Todd Press Conference.

Question: They are shooting ‘Harry Potter’ now. What is happening with Bellatrix?
CARTER: Well, hopefully in February I will have lost weight. She appears then and I’ve got some nice scenes with Alan Rickman.
Question: It’s book seven, so its a big one for her, I guess?
CARTER: Is seven the last one?
Question: Yeah.
CARTER: Yeah, I’ve got more stuff to do in that one.
Question: Have you read it?
CARTER: Yeah, of course I did. I was thinking ‘How big of a part do I have here?’ [Laughs]
