Some of the wittiest, most sophisticated comedies of the 1920s, '30s, and '40s, WNYC's Sara Fishko tells us, were directed by Ernst Lubitsch - who was the idol of his fellow directors during Hollywood's Golden Age. A new book aims to re-introduce us to his films. More, in this episode of Fishko Files.

Joseph McBride's book How Did Lubitsch Do It? is available now from Columbia University Press and on Amazon.
