Above all, no psychology!

Luis Bunuel was 67 when he made Belle de Jour; 72 when he made Discreet Charm of the Bourgeoisie; 74 for The Phantom of Liberty. Jeanne Moreau called him 'the only director I know who never threw away a shot. He had the film in his mind. When he said "action" and "cut," you knew that what was in between the two would be printed.'

Catherine Deneuve: 'He had a wonderful sense of humor. One thing he stressed was, "Above all, no psychology!" I accepted it wholeheartedly, especially because it came from him.'

Michel Piccoli: "He was severe in life and very hard to please. He was a great Spanish bourgeois by birth, and very well organised. He was very good about working within the budget, because when he was young, he had experienced economic hardship, especially in the U.S. He lived very modestly... He was once interviewed in Spain by French TV, which sent a crew with two trucks. He told them, "I could make a film with what it cost you to bring all this here."
