Martin Sheen is one of the busiest, most conscientious actors in Hollywood, putting together an extraordinary body of work. He became established playing youths run amok, and though his resume boasts its share of villains, he has grown over the years into a patriarchal figure, whose social responsibility are in keeping with his very liberal Catholic activism. A fervent promoter of the principles of Catholic social thought in word and in action, Martin Sheen’s passion for activism and its necessary place in today's political, humanitarian and social arenas has inspired generations. For over four decades, he has been an ardent supporter of causes that advocate peace and encourage justice throughout the world.
