David O. Selznick was a major Hollywood mogul, producing great films such as Gone with the Wind and Spellbound. But he was also a workaholic micromanager, obsessed with sending office memos. Through his memos, Selznick dictated every detail of production at his movie studio, from the size of Rhett Butler’s collars to Alfred Hitchcock’s camera angles. Produced by Erick Molinsky.
