The man who has stolen in order never to thieve again remains a thief. Nobody who has ever betrayed his principles can have a pure relationship with life. Therefore when a film-maker says he will produce a pot-boiler in order to give himself the strength and the means to make the film of his dreams - that is so much deception, or worse, self-deception. He will never now make his film.
From "Sculpting in Time" by Andrei Tarkovsky
