An Adventure in Time and Space- 9pm, BBC2
Every major sci-fi franchise needs an origins story and you might like to think of this 50th anniversary tribute to Doctor Who as a something of the kind. The difference is that An Adventure in Space and Time, a drama about the early days of the BBC series, takes place not in the fictional universe of the show, but in the real world. Mostly.
It’s part a 60s-set workplace drama, like Mad Men or The Hour, in which ambitious young women bang their perfectly coiffed beehives against the era’s glass ceiling, and part a fascinating making-of doc. Did you know that producer Verity Lambert, was at that time the only female producer at the BBC? And that director Waris Hussein was the first Indian-born director?
This story really belongs to the First Doctor, however. William Hartnell can be cantankerous old codger, but he's played with pathos and empathy by David Bradley. How will he cope when old age and ill health forces him to give up the role he loves? Luckily, in Doctor Who an end is always a beginning, and so it is with Mark Gatiss’ cleverly resonant script.
