Last of a special three-part presentation in which American director Billy Wilder discusses his career. He remembers working with Marilyn Monroe on Some Like It Hot
"With Monroe life was a surprise - sometimes she knew eight pages of dialogue by heart, sometimes she had a total block." He discusses the craft of screenwriting, the problems of working with Raymond Chandler and Agatha Christie, and the creative pleasure of improvising with his lifelong collaborator, I.A.L. Diamond.
