Director at Work: These pictures take you behind the scenes of Bluebeard's Eighth Wife to show you some of the secrets of the famous Lubitsch touch. Here Ernst Lubitsch is demonstrating how Gary Cooper she put on dressing gown -- or may be it's the pyjama coat that plays such a big part in the picture. You see, Gary is a millionaire who goes into a shop in the French Riviera to buy pyjamas and insists he wants only the tops, and -- anyway, the pictures show Lubitsch at work. With him are Gary Cooper, Claudette Colbert and the script girl, who holds the screenplay for his guidance. April 15, 1940.
