When Doctor Who returned to begin the era of the Third Doctor, with the episode Spearhead from Space, it really started with a bang. This episode introduced the Autons and the Nestenes, and I am struck by the fact that when Doctor Who started up again after its long break, the writers and producers chose to start again with that same foe. Perhaps it was the resounding success of the era of Jon Pertwee playing the Doctor, which injected new life (as well as technicolor) into the show in that time.
I do not recall ever seeing this episode before now. It was delightful to see Jon Pertwee trying to keep something of the spirit of Patrick Troughton’s frequently comical portrayal of the Doctor alive in his performance. I’ve seen many episodes from the Pertwee era, and the Third Doctor always seemed to me a much more severe and serious character than Troughton’s rendition before him or Tom Baker’s after him, more so than any other, perhaps even William Hartnell, who for all his severity had a whimsical streak.
The episode introduced the character of Liz Shaw, a skeptical scientist reminiscent of the character of Dana Scully on the X-Files. Indeed, the way the Brigadier explained UNIT to her made it seem very much like that Fox Mulder’s branch of the FBI, or Torchwood.
This is a great episode, and one that no Doctor Who fan should fail to see. The idea of the Doctor being stuck on Earth for the foreseeable future took the show in a new direction, even though it would not be long until the Doctor was able to get his TARDIS working again. That it was not working properly was of course par for the course from the beginning of the show, and so this was perhaps a less radical change of direction than the one that would be introduced later, namely that of the Doctor having a properly-working TARDIS and being able to choose where to go, and return back to where he had been.
