Actress Helena Bonham Carter is confident her character in SWEENEY TODD could be the next top celebrity chef. The star plays murdering landlady Mrs Lovett in the new movie, and has likened her role to that of U.S. lifestyle queen Martha Stewart - regardless of Lovett's dark side. She says, "I did have a few pie lessons. I love cooking but although I can't say I'm a brilliant cook - but better than her. "I had to learn how to make a pie. That was tricky, the whole pie making and singing at the same time. I wanted Mrs Lovett to be a bit Martha Stewart. She should have her own cooking show. It'd be nice, a recipe book definitely."
