Dario Fo is unique in world theatre. Playwright, actor, clown, teacher and philosopher, he is an international celebrity with two West-End smash hits to his credit - Can Pay? Won't Pay! and Accidental Death of an Anarchist. He is also a passionate collector of theatre history and a great hero of the Italian Left. Arena filmed Dario Fo against the background of medieval Italy, working with students in Umbria, at home in Milan and against the colourful backdrop of the Venice Carnival, where he performed his triumphant one-man comic show, Mistero Buffo.
