In this, Fritz Lang"s first sound film, Peter Lorre delivers a haunting performance as the cinema"s first serial killer, a whistling pedophile hunted by the police and brought to trial by the forces of the Berlin underworld. Greig"s "Peer Gynt Suite" will never sound the same. Criterion is proud to present Lang"s seminal film in a new transfer.
