Written by Douglas Adams, this was one of several ideas that Adams proposed to the production office around 1976. It was rejected by script editor Robert Holmes, who nonetheless encouraged Adams to continue submitting material; this ultimately led to his commission for "The Pirate Planet". In 1980, Adams revised "The Krikkitmen" for use by Paramount Pictures as a potential "Doctor Who" feature film, although nothing came of this project. Finally, Adams included many of the ideas from "The Krikkitmen" in his novel "Life, the Universe and Everything", the second sequel to his "The Hitch-Hiker's Guide to the Galaxy". A novel adaptation of the "Doctor Who" version by James Goss was released by BBC Books in January 2018.
