Sarah Montague speaks to actor and activist Michael Sheen. Known around the world for his film, television and theatre work, Michael Sheen made his name for his uncanny ability to portray other people, such as Tony Blair, Brian Clough and David Frost. These roles catapulted him into a life far from his home in Port Talbot in South Wales. But it was acting that also brought him back there, where he is now immersed in tackling some of the problems that face a poor community: poverty, debt and homelessness. How does he straddle such contrasting worlds?
