Green screen

Another oldie from 2011, first-time posting on this blog. If you aren't familiar with the 1973 sci-fi film "Soylent Green," you won't get this, but to destroy the joke and spoil the film in one sentence, the movie was about a future United States society wherein the government was supplying a food source whose secret ingredient was human flesh from people who were being harvested for that purpose. Furthermore, if you don't know what a green screen is, this isn't your cup of tea either.
