Soylent Green is a 1973 American dystopian thriller film directed by Richard Fleischer and starring Charlton Heston and Leigh Taylor-Young. Edward G. Robinson appears in his final film. 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.

In 1973, it won the Nebula Award for Best Dramatic Presentation and the Saturn Award for Best Science Fiction Film.
