The story of the making of Soylent Green, a masterpiece of social science fiction, released in 1973. Directed by Richard Fleischer and starring Charlton Heston and Edward G. Robinson, it deals not with an exogenous threat, such as an extraterrestrial attack, but with the dire consequences of an irreversible environmental catastrophe for which mankind alone is responsible.
