You already now something of Fritz Lang or you would not be reading this. Lotte Eisner goes further in depth in which Fritz is and what he has accomplished through the years. There is a small Fritz Lang: Autobiography
Then the book is chronologically divided between the German years 1919-1933 and the American period of 1936-1956. Then it goes to the German years of 1959-60. Because I have a large collection of German silent films this book is a must in helping understand those messages that are not intrinsic to the viewer.
