Dr Who 6.45pm, BBC One
It’s an old Police Box!” And so it is. The question is: where is it? Last week’s opening episode ended with the Doctor (Jodie Whittaker) and her new chums Graham (Bradley Walsh), Ryan (Tosin Cole) and Yasmin (Mandip Gill) dumped unexpectedly into deep space on the trail of the missing blue box. Tonight’s fairly excellent little adventure picks up exactly where we left off, as the human trio find themselves visiting an alien planet for the first time. But it’s a very desolate place, and there are dangers lurking everywhere (including some monsters that might have given MR James the vapours). Good stuff, with hints of bigger mysteries to come, Whittaker effortlessly in her stride, Bradley Walsh being fantastic, and some lovely missing-Tardis action.
