"The scene in which the scientist becomes cosmic energy and his wife grabs him and brings him back to human form is straight out of my Dyadic Cyclone (1976) … As for the scientist's regression into an ape-like being, the late Dr. Craig Enright, who started me on K (ketamine) while taking a trip with me here by the isolation tank, suddenly "became" a chimp, jumping up and down and hollering for twenty-five minutes. Watching him, I was frightened. I asked him later, "Where the hell were you?" He said, "I became a pre-hominid, and I was in a tree. A leopard was trying to get me. So I was trying to scare him away." The manuscript of The Scientist (1978) was in the hands of Bantam, the publishers. The head of Bantam called and said, "Paddy Chayefsky would like to read your manuscript. Will you give him your permission?" I said, "Only if he calls me and asks permission." He didn't call. But he probably read the manuscript."
