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 in his final film role.

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

Thorn is tasked with investigating the murder of the wealthy and influential William R. Simonson, a board member of the Soylent Corporation, which he suspects was an assassination.
