Once again, Doctor Who is here to wish you a Merry Christmas

Here’s what’s up in the world of TV for Sunday, December 25. All times are Eastern.
Top picks
Doctor Who: The Return Of Doctor Mysterio (BBC America, 9 p.m.): Merry Christmas everybody! We all hope that your respective holiday celebrations are treating you well and that you’re not suffering too much from the fact that there’s nothing new on television. If you are, the BBC has a present for you with the latest in the grand tradition of Doctor Who Christmas specials. It’s an even more welcome gift this year given that we haven’t seen the Doctor since last Christmas (no, not “Last Christmas”) in “The Husbands Of River Song,” and absence has made the heart grow fonder. Tonight, Peter Capaldi’s Twelfth Doctor and Matt Lucas’ Nardole team up with a reporter (Wolf Hall’s Charity Wakefield) and a superhero called the Ghost (Shameless’s Justin Chatwin) to save New York City from brain-swapping aliens. Alasdair Wilkins was already happy to make an overdue return to the TARDIS, but adding superheroes just sweetens the deal.
The Hollow Crown: Richard III (PBS, 9 p.m.): Part three of The War Of The Roses concludes tonight, as the crown rests securely on the head of Benedict Cumberbatch’s Richard III. As to the security of the head it’s resting on, well… let’s just say there’s a reason that this play is counted amongst Shakespeare’s tragedies and not his comedies.
Premieres and finales
Call The Midwife (PBS, 7:30 p.m.): The BBC continues to save us from the vast wasteland of holiday programming with another Christmas special, this one for Call The Midwife. The ladies of Nonnatus House are out of their comfort zones this holiday season as they travel to South Africa in an effort to save a clinic in jeopardy.
