Twice Upon a Time was the 2017 Doctor Who Christmas special. It was the final episode under showrunner Steven Moffat's tenure, and featured the regeneration of Peter Capaldi's Twelfth Doctor, into Jodie Whittaker's Thirteenth.

The First Doctor had his first full appearance on the programme since The Five Doctors. Here, he was portrayed by David Bradley, who had previously played William Hartnell himself in An Adventure in Space and Time. This was the first televised interaction between a "classic" Doctor and a BBC Wales era Doctor since 2007's Time Crash. Archival footage from The Tenth Planet is used to bookmark the First Doctor's place in this story. This was the final adventure for both the First and Twelfth Doctors. Both, in the end, regenerate into their next incarnations. The special also introduced Captain Archibald, a new member of the Lethbridge-Stewart family.

Ben Jackson and Polly Wright make a brief re-reappearance in the programme for the first time since their exit in 1967's The Faceless Ones. Bill Potts joins the two Doctors, and Captain Lethbridge-Stewart, as a Testimony glass avatar. Past companions Nardole and Clara, briefly, make similar appearances. The "good Dalek" Rusty, from Capaldi's second episode, Into the Dalek, makes his second appearance.

Synopsis

Two Doctors stranded in a foreboding snowscape, refusing to face regeneration. In the final chapter of the Twelfth Doctor's adventure, he must face his past to decide his future. It is the end of an era, but the Doctor's journey is only just beginning...

Story notes

• The Twelfth Doctor's regeneration has a new visual effect, and even sound effect, to those used previously in the BBC Wales series. This the first regeneration for the Doctor, since the Seventh Doctor's in 1996, to use an effect which is visually distinct from that seen in The Parting of the Ways, with the Ninth Doctor.
