George Clayton Johnson (July 10, 1929 – December 25, 2015) was an American science fiction writer, best known for co-writing with William F. Nolan the novel Logan's Run, the basis for the MGM 1976 film. He was also known for his television scripts for The Twilight Zone (including "Nothing in the Dark", "Kick the Can", "A Game of Pool", and "A Penny for Your Thoughts"), and the first telecast episode of Star Trek, entitled "The Man Trap". He also wrote the story and screenplay on which the 1960 and 2001 films Ocean's Eleven were based. Early life Johnson was born in a barn in Cheyenne, Wyoming, was forced to repeat the sixth grade, and dropped out of school entirely in the eighth. He briefly served as a telegraph operator and draftsman in the United States Army, then enrolled at the Alabama Polytechnic Institute (now Auburn University) under the G.I. Bill, but quit to return to his travels around the U.S., working as a draftsman, before becoming a writer. Writing career In 1959, Johnson wrote the story "I'll Take Care of You" for Alfred Hitchcock Presents. From 1959 onward, Johnson's work began to regularly appear in magazines such as Playboy, Los Angeles, The Twilight Zone Magazine, Rogue, and Gamma, and he began to write stories and scripts for TV. In 1960, he co-wrote the treatment (with Jack Golden Russell) for the Rat Pack film Ocean's 11, although most of the details were changed for the actual film. Later, Johnson joined the Southern California School of Writers that included, among others, William F. Nolan, Charles Beaumont, Richard Matheson and Ray Bradbury. Through them he met Rod Serling, to whom he sold his story "All of Us Are Dying", which was produced as "The Four of Us Are Dying", scripted by Serling. Eventually, after selling other stories and having them scripted by other writers for the show, Johnson asked Serling to let him attempt a teleplay for the series, which was "A Penny for Your Thoughts". Later, after completing more scripts for The Twilight Zone, he worked as a writer for other television series, including Honey West, Wanted Dead or Alive, Route 66 and Kung Fu.
