The opening sequence of the 1931 film 'M' establishes conventions of film noir through its use of black and white cinematography, ominous music, and shadows. It introduces the director and then shows innocent children playing and foreshadowing danger from "the nasty man in black". Shots of a mother and her daughter establish characters before visual and audio cues hint that a murder may soon occur. A poster advertising a wanted criminal and the shadowy figure it depicts heighten the mystery and suspense.
