Of all Fritz Lang's creations, none have been more innovative or influential than M, the film that launched German cinema into the sound era with stunning sophistication and mesmerising artistry. A spate of child killings has stricken a terrified Berlin. Peter Lorre gives a legendary performance as the murderer Hans Beckert, who soon finds himself chased by all levels of society.

From cinema's first serial killer hunt, Lang pulls back to encompass social tapestry, police procedural, and underworld conspiracies in an astonishingly multi-faceted and level-headed look at a deeply incendiary topic. One of the greatest psychological thrillers of all time, M remains as fresh and startling almost 80 years on.

M has been announced for a simultaneous 2-disc DVD and single-disc Blu-ray release from Eureka as part of the Masters of Cinema series on 22nd February 2010 at the RRP of £19.99 for the DVD and £24.99 for the Blu-ray.
