Litz Pisk was widely regarded as the most influential teacher of modern theatre movement of the 20th century. She innovated and advocated a physical training that sought to combine awareness, emotion and imagination specifically for the actor's craft. Her seminal book, 'The Actor and His Body', is the direct result of her unique dual career as a professional movement director and as an actor movement teacher working in leading British conservatoires. Pisk's quest was to find expression for the inner impulse that motivated actors to move. Her teachings, as outlined in this book, offer insight on the specific craft of the actor, and the relationship between movement, imagination and the 'need' to move.
