"William Friedkin had a shotgun with blank shells that he'd shoot off on the sound stage during breaks, while filming The Exorcist. It scared the daylights out of everybody, and after a few times he was asked to stop. The actors didn't find it funny. What they didn't know was that their reactions were being filmed - and later inserted into the movie as their reaction when Regan made a sound upstairs."

"In "Soylent Green", when Sol Roth (Edward G. Robinson) reads the Soylent Corporation Oceanographic Report from 2015-2019, he realizes that the oceans are dead and that Soylent Green HAD to be made from corpses. So he goes to a Euthanasia Parlor. When Thorne (Charlton Heston) catches up to him, and is talking to him about "things", Thorne has tears in his eyes. This is because he was the only one on the set that knew that Robinson was, in fact, dying of cancer, and died 12 days after the filming ended."
