Film critic Dana Stevens took her love for Silent Movie Era star Buster Keaton and told the story of the 20th century film industry as it evolved alongside Buster’s own life. Marc talks with Dana about her new book, Camera Man, which is not just a biography of Keaton. It’s a look at the politics of film, the beginning of the studio system, the start of film criticism, the rise and fall of early movie stars, and how America dealt with the seismic change that was ushered in by this new art form.
