Funnyman Sacha Baron Cohen has been banned from singing in Tim Burton�s film adaptation of �Sweeney Todd, The Demon Barber of Fleet Street�.
In the film Sacha plays the role of Signor Adolfo Pirelli, Sweeney�s hairdressing rival, but Sacha cannot sing, so is having to use his voice to his best ability in the musical.
A source told the Sun: �Pirelli is a notoriously demanding role with some difficult songs.
�Any professional singer would struggle. So Sacha has been told to go for a rap style. It will be a bit like Jim Broadbent�s performance in �Moulin Rouge�. That won him a Bafta.
�He is going to do a fantastic job. But he couldn�t cut it with the singing. His voice was too low.�
This film will be one of the best of 2007; Johnny Depp is playing the murderous barber Sweeny Toss while Helena Bonham Carter is playing Mrs Lovett, the baker.
