7 SWEENEY TODD: THE DEMON BARBER OF FLEET STREET (2007)
Another film directed by Burton, this musical horror adaptation of Stephen Sondheim and Hugh Wheeler’s Tony Award-winning 1979 musical follows the story of the titular barber and serial killer, who kills his customers and has his accomplice Mrs Lovett (Bonham Carter) process the corpses into meat pies.
The actress apparently sent Sondheim over a dozen audition tapes of her singing in order to quash any rumours of nepotism in the casting process, since Bonham Carter and Burton have been in a romantic relationship since 2001. He was impressed with her vocals and gave his approval. She received a Golden Globe nomination for Best Actress Motion Picture Musical or Comedy.
