The Angarath (unproduced TV story)
The Angarath was an unproduced story concerning a race of people offering human sacrifices to sentient rocks.
On 11 August 1975, Eric Pringle was commissioned for the first two episodes of The Angarath by producer Philip Hinchcliffe. These were delivered on 27 September but after receiving no reply from the Doctor Who production office as to their suitability, Pringle eventually decided to complete the serial regardless, submitting the final two parts on 10 March 1976. Hinchcliffe had no intention of proceeding further with the story, however, and the situation was finally dealt with on 23 June the same year.
Several years later, Pringle would write The Awakening for Season 21.
