Attention!
Clip contains adult language.

Helena Bonham Carter, Johnny Depp, Tim Burton, Alan Rickman and Timothy Spall talk about their latest movie "Sweeney Todd: The Demon Barber of Fleet Street".
In the course of the press conference Helena Bonham Carter answers the question what made her go for the role as Mrs. Lovett although her husband is directing the movie. Furthermore, Alan Rickman is being asked how he's been preparing himself for his role, where he obviously has quite a lot singing to do.
