Soylent Green

21st century New York City is (still) an overpopulated mess, and the only food left is Soylent Green, a soyabean and lentil concoction with an extra-special, government-mandated ingredient. As police detective Thorn (Charlton Heston) investigates a murder, he learns of a conspiracy with bizarre implications and discovers the horrifying truth about Soylent Green's secret ingredient. This is Edward G. Robinson's final movie, as the star died not long after filming his final scene. Based on Harry Harrison's "Make Room! Make Room!"
