For Musings, I wrote about Samson Raphaelson, a playwright and screenwriter most notable for his nine-film collaboration with Ernst Lubitsch. I discovered Raphaelson after watching the Criterion release of 1943’s Heaven Can Wait, which featured among its extras a thirty-minute PBS documentary about Raphaelson, who was then in his 80s. He came at the screen a man possessed, shaking his hands and extolling the virtue in screenplays of human characteristics above all else. To say I fell somewhat in love would not be inaccurate. He wrote a book called The Human Nature of Playwriting1, drawn from a course he taught in 1948, that’s just as illuminating.
