Doctor Who episode 688: Battlefield – Part One (6/9/1989)
‘Sideways in time, across the boundaries that divide one universe from another.’ Some of the details in this are brilliant: the Brigadier ending up with Doris; a genuinely internationally-flavoured UNIT and some effort put into getting a more diverse cast; futuristic hints like ‘the King’ and carphones, the little robot coin that could just have been a lump of colourful plastic, but suggests a level of attentiveness and care behind the scenes. Nicholas Courtney’s performance is superb: the moment he tells Doris kindly but firmly, ‘I’m not playing’ at soldiers is very moving. He’s not just “the Brigadier” showing up to tick a continuity box, we get a sense of a man with a life that we haven’t really had since the end of Season Eight.
