Catholic actor Martin Sheen is Kirsty Young's guest on Desert Island Discs this Sunday.
In recent years he has won great acclaim and a Golden Globe for playing the leader of the free world in the hugely successful political drama The West Wing.
He's made more than 100 movies, including Apocalypse Now, Badlands and The Departed. For him, work is often a family affair, in Wall Street he acted alongside his son Charlie Sheen and in his forthcoming film, The Way, set on the Camino de Santiago, he was directed by another of his children - Emilio Estevez.
But away from the film set, Martin has been a peace and human rights activist and campaigner. He's been arrested more than 70 times and is motivated by his Catholic faith and conscience.
The programme will be first broadcast on Sunday, 3 April 2011 at 11.15am on BBC Radio 4
