Soylent Green is a 1973 American science fiction film directed by Richard Fleischer and starring Charlton Heston and, in his final film, Edward G. Robinson. The film overlays the police procedural and science fiction genres as it depicts the investigation into the murder of a wealthy businessman in a dystopian future suffering from pollution, overpopulation, depleted resources, poverty, dying oceans, and a hot climate due to the greenhouse effect. Much of the population survives on processed food rations, including "soylent green".
