Murnau, of course, wasn't the only German-speaking filmmaker to find a home in the US between the 1920s and 1940s: from William Wyler to Billy Wilder to Max Ophüls to Otto Preminger, that particular immigrant demographic accounts for much of the most glistening output of Hollywood's golden age. "Metropolis" director Fritz Lang was a particularly estimable exile, shaping mid-century noir with such films as "The Woman in the Window" and "The Big Heat," but his lean, mean, appropriately titled Hollywood debut "Fury" remains under-seen and undervalued: starring Spencer Tracy in one of his strongest performances as an innocent man seeking revenge on his lynch mob, it still positively bristles with outsider anguish.
