The name of Fritz Lang—the visionary director of Metropolis, M, Fury, The Big Heat, and thirty other unforgettable films—is hallowed the world over. But what lurks behind his greatest legends and his genius as a filmmaker? Patrick McGilligan, placed among "the front rank of film biographers" by the Washington Post, spent four years in Europe and America interviewing Lang's dying contemporaries, researching government and film archives, and investigating the intriguing life story of Fritz Lang. This critically acclaimed biography—lauded as one of the year's best nonfiction books by Publishers Weekly—reconstructs the compelling, flawed human being behind the monster with the monocle.
