Gough had been a guest star a few years back, some sort of possible BBC rules issues preventing his casting. Never stopped Colin Baker getting the job though.
Thanks for telling me.
Yes, Michael Gough was the Celestial Toymaker. However, by the time Troughton left the Tardis there must have been may actors that had played more than one part on the show. Nicholas Courtney is the only one that springs immediately to mind.Gough had been a guest star a few years back, some sort of possible BBC rules issues preventing his casting.

Although Fulton Mackay would have been a great doctor, I'm glad he accepted the role in Porridge, which IMHO was the finest hour of his career, with him going head to head with Burt Lancaster in Local Hero (also starring Peter Capaldi) as his second. As I've also mentioned Michael Gough and Frederick Jaeger in The Avengers episode The Cybernauts, I'll also mention that Mackay was very good in Return of the Cybernauts.
