" The eye of the movie camera is an evil eye. When you act in front of it, that cyclops keeps taking from you, until you feel empty. On the stage, you give something to the audience, more comes back. When the curtain comes down in a theater, you have a feeling of exhilaration - something's been completed, fulfilled. It's so different from an exhausting day of shooting at the studio. You come home tired, drained. Making a =movie is like making a mosaic - laboriously putting little pieces together, jumping from one part of the picture to another, never seeing the whole, whereas in a ply, the momentum of the continuity works with you, takes you along. Doing a play is like dancing to music. Making a movie is like dancing in wet cement. "

― Kirk Douglas , The Ragman's Son
