"Richard Barsam has given us as comprehensive a study of the origins and development of the nonfiction mode in motion pictures as we are ever likely to have in one volume. He draws on all the major written sources and many which are little known, and he shares with us many eloquent descriptions of the films themselves, giving us a valuable textbook." -Richard Dyer MacCann"... superb work...
