The trailer (below), which dropped during the annual Christmas Special “Joy to the World,” features a first look at the new batch of episodes starring Gatwa (Netflix’s Sex Education) as the Fifteenth Doctor and Varada Sethu as the new TARDIS companion.

It’s not that Doctor Who’s festive episodes can’t be memorable; “The Husbands of River Song,” “A Christmas Carol,” “The Runaway Bride,” and more beg to differ. But I know it’s a holiday tradition in the U.

The Doctor is back for another holiday special. We'll show you where to watch the Doctor Who Christmas Special around the globe.

The TARDIS is as much a part of Christmas as turkey, mince pies, and mulled wine, and former "Doctor Who" showrunner Steven Moffat certainly knows his way around a festive adventure. This year's holiday offering, "Joy to the World", is the writer's ninth, and it comes with all the trimmings you'd expect.
