Mind of the Hodiac (unproduced TV story)
Mind of the Hodiac was an unproduced story for Doctor Who. It was initially drafted by Russell T Davies, being the very first Who script he ever worked on.[1] The story would've featured the Sixth Doctor and Melanie Bush.
When the original run for the series ended in 1989, Davies received a letter from Andrew Cartmel, saying "Thank you for your idea, I liked it and put it to one side for consideration but now we've closed down..."[2]
During the Doctor Who: Lockdown! watch-a-long for The Runaway Bride, Davies found a few pages of the script, and started sharing it online. Following that, Big Finish announced that they would produce an audio adaptation of the story.
