“If acting is a creative art–if it is–then it is perfectly reasonable to demand for it conditions similar to those of the painter or the writer: the right, that is, to make a mess, to splash around, to make drafts and sketches, to have a wasterpaper bin at your side. In any creative activity, art is madness, craft is sanity. The balance between them makes the work.”
Simon Callow, Charles Laughton: A Difficult Actor
