It's twice the Doctors, twice the TARDIS(es?), and twice the trouble, in the first trailer for the upcoming Doctor Who Christmas special, "Twice Upon A Time."
We get a look at Peter Capaldi's Doctor teaming up with the first Doctor (played here by David Bradley) for one last adventure before handing over the keys to the TARDIS. The footage here reveals the Doctor(s) will be trapped in one moment, with producer Mark Gatiss (Sherlock) popping up in a supporting role. Oh, and in case you were worried Bill (Pearl Mackie) might be gone, we can confirm she will also be back for Capaldi's farewell special.
Doctor Who "Twice Upon A Time" will air this Christmas.
