During spare time in filming, Tom Baker (the Fourth Doctor) and Ian Marter (Harry Sullivan), who later novelised several "Doctor Who" scripts for Target Books, wrote a script for a "Doctor Who" film which they entitled "Doctor Who Meets Scratchman" (alternatively "Doctor Who and the Big Game"). The script saw the Doctor encounter the Devil (who called himself Harry Scratch or Scratchman), the Daleks, robots known as Cybors, scarecrows made from bones and, briefly, the Greek god Pan. At times Vincent Price and Twiggy were associated with the production. Price would have played the villain Harry Scratch and Twiggy a replacement female companion after Elisabeth Sladen had left the TV series.
