Written by James Follett, this involved monsters attacking a race of beings who live inside Halley's Comet, unaware that there is anything beyond it they believe that their world is the sum and total of the universe. "Into the Comet" would have used the companions of Romana and K9. Follett was a novelist who pitched this idea to script editor Douglas Adams circa September 1979 when they met up and discussed the forthcoming return of Halley's Comet. Though the storyline was rejected by Adams, Follett resubmitted "Into the Comet" to new script editor Christopher H. Bidmead around May 1980, but once again the storyline was not pursued.
