Actor Sacha Baron Cohen was so determined to give an accurate portrayal of a barber in SWEENEY TODD: THE DEMON BARBER OF FLEET STREET - he recruited his own personal stylist to give him lessons. The British star - who plays Italian coiffure Adolfo Pirelli in the film - even brought Sicilian-born barber Carmelo Guastella on to the set of the murder musical to ensure his shaving techniques were up to scratch. Guastella says, "Sacha's very professional. He takes his roles very seriously and does a lot of preparation, so much so that he commandeered me for four days to make sure he really looked like he was shaving on set. "Sacha did it marvellously, singing a complex song in an Italian accent while lifting the lather from his client's face like a professional. "He called me to his hotel only for me to find his driver sitting in a chair with foam all over his face and Sacha prancing around him with a blade and singing his song from the film."
