Well, hardly a specialist, sir, but I dabble. Yes, I dabble.
Doctor Who‘s third season ends as the entire series began, in 1960s London, and in many ways, the season’s final story, “The War Machines,” (Story Production Code BB) takes its meager strengths from being set in quite familiar surroundings. Ian Stuart Black’s tale of an artificial intelligence bent on destroying its organic creators could easily have transpired on some distant planetoid in the far future, but such a danger arising from a laboratory atop the newly completed Post Office Tower in London just at the point when computers were beginning to make inroads into public consciousness provides sufficient narrative impetus that we can almost ignore the sloppy plot.
Writing his second Doctor Who story, Ian Stuart Black again shows no sense of familiarity with (or worse, no respect for) the series’ norms and established precedents. The Elders in his “The Savages,” aired immediately prior to “The War Machines,” track the Doctor through space and time somehow, which the Doctor himself has not yet accomplished through three seasons, while here the villain of this story, the awakened computer WOTAN (Will Operating Thought Analogue), refers to the Doctor as, egads, “Doctor Who.” In “The Savages,” at least, Black has characters specifically note that they do not know the Doctor’s name; here, even henchmen spout the offending phrase:
Professor Brett: Top priority is to enlist Doctor Who. He has advanced knowledge which WOTAN needs. Doctor Who must be enlisted into our services tonight.
Much about this story suggests a break from past precedent and the dawn of a new era, as the production team was obviously complicit in this breach of naming protocol. After three seasons of not being able to get back to contemporary London, the TARDIS materializes there with nary a remark from the Doctor. He merely pops an “Out of Order” sign on the rather beat-up looking police box door and, sensing that something is very “alien” about the Post Office Tower, arranges confabs with the leading scientists and civil servants of the day.
We have no lead-in from a prior story—and no lead-out from this story to the next—to explain why and how the TARDIS has arrived at the next destination. The Doctor just shows up, senses something is wrong, fixes it (ostensibly because he has nothing better to do), and disappears. Even the interactions here with the military, a first, will become commonplace in the next eight seasons. A format has arrived. Even the episode titles are different, in a computer font with an animated effect. To go along with this change in sensibility, two new companions arrive, every bit products of ’60s London, and one companion is almost literally sent out to pasture.
And how does the Doctor fix a maniacal computer bent on the eradication of the human species? With punch cards, of course.
