The Automata (unproduced TV story)
From Tardis Wiki, the free Doctor Who reference
The Automata was an unproduced story for Season 11, to be written by Robert Holmes.
Holmes was commissioned to write a storyline for The Automata on 16 January 1973. It did not find favour with producer Barry Letts and script editor Terrance Dicks, however, and was rejected ten days later. Holmes was commissioned to write The Time Warrior instead.
