Summary: On moratorium since the end of March, Fritz Lang's serial killer thriller starring Peter Lorre returns to DVD in a fully restored, special edition double-disc set. A simple, haunting musical phrase whistled off-screen tells us that a young girl will be killed. "Who is the murderer?" pleads a nearby placard as serial killer Hans Beckert (Lorre) closes in on little Elsie Beckmann... In his harrowing masterwork, Lang merged trenchant social commentary with chilling suspense, creating a panorama of private madness and public hysteria that to this day remains the blueprint for the psychological thriller. The Criterion Collection is proud to present a new restoration of this landmark film in an all-new two-disc set, also including audio commentary by two German film scholars; an interview film Conversation with Fritz Lang, directed by William Friedkin (The Exorcist, The French Connection); a short film inspired by M by director Claude Chabrol (La Ceremonie, Les Biches); classroom tapes of M's editor discussing the film and its history; and much more.
