Alixion (unproduced TV story)
From Tardis Wiki, the free Doctor Who reference
Alixion was a story that was to have been a part of Season 27 had Doctor Who continued to be produced beyond Survival. It would have been written by Robin Mukherjee.
Alixion was a three-part story that had been commissioned for Season 26, but was not produced due to the relative greenness of the writer in terms of television drama writing at the time. [1]
Cast changes
This story was to have been the final story for Sylvester McCoy. For the role of the Eighth Doctor, the actor Richard Griffiths has been suggested as the actor the producers of the time would have cast. [2]
