Ray Russell (1924—1999) was a writer of short stories, novels, and screenplays. He is probably most well known for "Sardonicus," which appeared in the January 1961 issue of Playboy magazine, and was subsequently adapted by Russell into a screenplay for William Castle's film version, titled Mr. Sardonicus. Stephen King called Sardonicus "perhaps the finest example of the modern gothic ever written". "Sardonicus" was part of a trio of stories with "Sanguinarius" and "Sagittarius". Russell was also one of the screenwriters for Roger Corman's X (aka X: The Man With the X-Ray Eyes) and The Premature Burial (based on the Edgar Allan Poe short story).
