Looks like we won't be getting a Christmas or New Year special this year either, which is a bit of a shame as even in Tennant's final year when we didn't get a full series we still got specials at Christmas and other points - those been
The Next Doctor at Christmas,
Planet of the Dead at Easter,
The Waters of Mars in November and finally the Christmas/New Year's Eve two-parter
The End of Time.
Funnily enough regarding last year, I think I read a story (in
Metro if I'm not mistaken) that said that the writers working on Doctor Who had "run out of ideas" for Christmas episodes.
For me, this sounds like a load of tosh. If they truly have no ideas, they could have easily asked the fans about ideas for a Christmas special as I'm sure a good amount of the fanbase would have come up with ideas that were at the very least serviceable.
Heck, Youtuber Nerdrotic actually did that and he received hundreds of replies for potential stories. I can't show the whole thing as he does drop a few choice words but here's the cut section of some of the ideas that the fanbase offer:
Doctor Who Christmas Episode Ideas
I also came up with a few ideas for Christmas episodes, one of which was a homage to the birth of Jesus (with a human woman due to give birth to two children who are both children of the
Elder Gods and part of an important prophecy) but with elements of "
The Box of Delights" by John Masefield and of other mythologies such as Norse Mythology. Finally, it would feature the return of classic era villain
Fenric and his "
Wolves", who are determined to stop the prophecy at any and all costs as it concerns the eventually demise of Fenric himself.
An alternative idea would be for the Doctor telling three Christmas-related stories from her past incarnations that we haven't seen, with the background story been her and her companions preparing for Christmas together. You could maybe portray one in animation if it involves Doctors who are no longer around (heck, they got a new actor to play the First Doctor in
Twice Upon A Time) and maybe even bring back past Doctors from the classic/new series for some of the stories. It's said the 8th Doctor was there when Jesus was born and Paul McGann has said he would love it if the BBC invited him back to play the Doctor so that could be an interesting short story to see if the BBC will allow it.
On top of that, one of the ideas proposed by former showrunner Russell T. Davies before his tenure on Doctor Who ended was to have J.K.Rowling (the author of the
Harry Potter series and who he'd previously asked about potentially writing a Doctor Who episode, which she declined) star in a Christmas episode - with the episode becoming a Doctor Who/Harry Potter crossover thanks to an alien bug similar to the
Time Beetle latching onto JK's back and causing her imagination to manifest into reality - meaning the Doctor would likely team up with Harry Potter to battle Magical Beasts and Death Eaters.
