Book excerpt: From its earliest days, the Mafia has sought to make a fast buck from the American film industry. Stories of intimidation, threats and violence mingle with those of glamour and excess. In this stunning story of infamy and ballsy enterprise, Tim Adler tells the secret history of Al Capone, Sam Giancana and John Gotti's attempts to infiltrate the studio lots. However, although they have controlled the moguls and the money, the Mob learned how to be cool from classic films like The Godfather and characters like Tony Soprano, leaving them forever intertwined in both fact and fiction.
