This book was interesting on its own but not what i was expecting. Hardboiled Hollywood: The True Crime Stories Behind the Classic Noir Films by Max Decharne talks mainly about the way the writers and directors turned books into movies. a few chapters, on Little Caesar (Al Capone), Psycho (Ed Gein) and of course the ones on Bonnie and Clyde and Dillinger, do discuss the criminals but most chapters describe how the writer wrote the original book and how that was changed for the movie version. The early chapters also talk about the censorship rules of the 1920s-1940s and anti-Communist hunt in the 50s, which i didn't know much about. It isn't a bad book; it just didn't give me the information i wanted. a 4.
