I watched an old episode of Doctor Who tonight – part 2 from the episode “The Moonbase” from season 4, early in Patrick Troughton’s era. Episode 1 has been lost, although the audio survives. A great many episodes from the early years of Doctor Who – and in particular from Patrick Troughton’s time as the Doctor – have been lost or damaged so as to be unwatchable. This is unfortunate, since the Second Doctor was the one to really develop the Doctor’s comical side, in a way that would inspire Tom Baker and, more recently, Matt Smith.
I suspect that, when animating them, it would be possible to also introduce color, update the appearance of the cybermen, and in various ways improve the special effects beyond what was possible in a live action show in 1967.
If this were to be done, and done well, I could see children today appreciating the older series. I could see early Doctor Who “regenerating” and developing a young fan base.
