Description: M is a 1931 German drama-thriller directed by Fritz Lang and written by Lang and his wife Thea von Harbou. It was Lang's first sound film, although he had directed over a dozen films previously, including Metropolis. Over the years the film has become a defining classic that rivals Lang's other works for the title of magnum opus. Lang himself maintained that this film was his finest work.[1][2] The lead, Peter Lorre, was typecast for years after the film's release as a villain for his portrayal of a child murderer. M also pioneered the use of leitmotif to give the film score a more intense feel.
