Films that involve child murders and pedophilles are not issues that people want to see on the big screen. Some films manage to be sucessful because they only mention what happened instead of showing it. Also they don't make the whole movie about the incident only. Plots in these films are also successful because it is based on reality.

   Who Saw Her Die? is a film in which there is a search for a person who murdered two young girls with red hair. A womans face stays hidden until the end and she seems to be a culprit. Another film that depicts another serial child murder is Don't Tourture a Duckling. They are trying to find out who committed the murders against young delinquent boys and are on a witch hunt to find the murderer.

   Both these films relate to M because they restrain from showing the graphic details of the child murders which make it a more capitulated film to watch. In the M all the murders occurred off screen. They focus on how they are going to catch the killer and with the help of society, which take it upon themselves to take matters into their own hands.
