Soylent Green (1973)
Soylent Green is a 1973 American science fiction film directed by Richard Fleischer and starring Charlton Heston, Leigh Taylor-Young, and, in his final film, Edward G. Robinson. The film combines the police procedural and science fiction genres, depicting the investigation into the murder of a wealthy businessman in a dystopian future suffering from pollution, overpopulation, depleted resources, poverty, dying oceans, and all year humidity due to the greenhouse effect. Much of the population survives on processed food rations, including "soylent green". The film, which is closely based upon the 1966 science fiction novel Make Room! Make Room! by Harry Harrison, won the Nebula Award for Best Dramatic Presentation and the Saturn Award for Best Science Fiction Film in 1973.
