Soylent Green is a 1973 American ecological dystopian thriller film directed by Richard Fleischer and starring Charlton Heston, Leigh Taylor-Young, and Edward G. Robinson. Loosely based on the 1966 science fiction novel Make Room! Make Room! by Harry Harrison, it combines both police procedural and science fiction genres: the investigation into the murder of a wealthy businessman; and a dystopian future of dying oceans and year-round humidity due to the greenhouse effect, resulting in suffering from pollution, poverty, overpopulation, euthanasia, and depleted resources.
