Development In November 2022, Davies was quoted in
Doctor Who Magazine as having written a further special episode outside of the 60th anniversary specials. It is the first
Doctor Who Christmas special since "
Twice Upon a Time" (2017) after the programme temporarily transitioned New Year's specials from 2018 to 2022 under the preceding showrunner
Chris Chibnall. Davies also said that when creating the goblins he wanted to lean more into the
supernatural and unexplainable side of
Doctor Who the programme was not able to previously explore. The read through for the episode took place on 12 January 2023. The unnamed television programme Ruby appears on was inspired by
Long Lost Family, which is also hosted by McCall. The
Long Lost Family production team assisted in its depiction in "The Church on Ruby Road". When designing the goblin band's outfits, costume designer Pam Downe ensured that each goblin had their own "complete personality and specific look", rather than having "generic" appearances. Orchestral recordings for the episode took place at the
Wales Millennium Centre in January 2023 with the
BBC National Orchestra of Wales.
Murray Gold cited
Aladdin as inspiration when composing music for "
The Goblin Song". The episode's title and official airdate were announced via a
Disney+ press release on 5 November 2023.
Filming was used as the titular church on Ruby Road. "The Church on Ruby Road" was directed by
Mark Tonderai who previously directed the
eleventh series episodes "
The Ghost Monument" and "
Rosa" (both 2018). It was filmed along with the
fourteenth series in the series' stand-alone second production block. The episode was also the third of the fourteenth series to be filmed, following the series' fifth episode, "
Dot and Bubble", and preceding the series premiere, "
Space Babies". Filming on the goblin ship set occurred on 20 February 2023. Only 12–15 extras were used as goblins for those scenes. It took five people to control the King Goblin prop during filming. The production team continuously changed their outfits and relocated them around the set to make the number appear larger. Additional filming there also took place from 14 February. Soap foam and paper was used to create fake snow for this scene. The top of the church's steeple was replicated on a
soundstage at
Wolf Studios Wales. "The Goblin Song" was filmed on a
green screen on 3 March 2023.
Casting On 8 May 2022,
Ncuti Gatwa was announced as
Jodie Whittaker's successor as the programme's lead, and many reports, including that of the BBC itself stated he would play the Fourteenth Doctor and that Whittaker's
Thirteenth Doctor would regenerate into an incarnation portrayed by Gatwa. Later clarification announced that Gatwa would actually portray the
Fifteenth Doctor, with the Fourteenth portrayed by
David Tennant for the
2023 specials. Auditions for the next companion took place on 24 September 2022. On 18 November 2022, during
Children in Need,
Millie Gibson was announced as the new companion
Ruby Sunday. On 30 November 2023, it was announced that
Davina McCall would be cast as herself in the special, and that
Michelle Greenidge,
Angela Wynter, and
Anita Dobson had been cast as Carla, Ruby Sunday's mother; Cherry, Ruby Sunday's grandmother; and Mrs Flood respectively.
Susan Twist appears uncredited as a heckler at Ruby's band's concert, after appearing as Mrs Merridew in "
Wild Blue Yonder" (2023). Her return appearance caused fans to speculate that she would appear again in future episodes. == Broadcast and reception ==
