We may not know what Capaldi's costume will ultimately be, but we do know what sort of pyjamas he wears. See also -- a horse.
It's always a bit dodgy to show footage filmed on the set of Doctor Who. On the one hand, we want to know what's coming. On the other hand, we don't want to be spoiled and then have to wait most of the year to actually see an episode.
But some things are small, spoil very little, and are quite fun. In that sprit we present the following video showing Peter Capaldi, wearing his pajamas and riding a fake horse. As one does.
Judging by that bit of footage, it's possible that working the TARDIS may not be the only thing the Twelfth Doctor's forgotten how to do. Considering the jimjams, though, might we recommend a quick cup of tea and a satsuma, perhaps? Worked wonders for the Tenth Doctor.
