Doctor Who Christmas Special Canceled as Russell T Davies Leaves the BBC Show

BBC has canceled the planned 2026 Christmas special of Doctor Who as it prepares to reshape the long-running sci-fi series. Showrunner Russell T Davies has also announced that he is leaving the show.

The broadcaster said the decision was made after “careful consideration” and acknowledged that it would disappoint fans. The special had been announced last year as a festive episode meant to bridge the gap before the next stage of the series.

Instead, BBC will put Doctor Who out to competitive tender, inviting production companies to bid for the chance to help produce future seasons. The corporation said the move was part of securing “the next phase of the show for future generations.”

Davies confirmed his departure on Instagram, calling it “goodbye from me but hello to a big new future for the show.”

He said the Christmas episode had only been planned as a way to protect the show’s future while its next steps were still uncertain.

“We only cooked that up to guarantee a future when no one knew what would happen, but now we do know, there's no need for it,” he wrote.

Davies added that fans would have to wait longer for new Doctor Who, but said the delay would lead to “more Doctor Who than a one-off.”

He also pushed back against speculation, saying there had been no script and that no actor had been approached to play the next Doctor.

The last season aired in May 2025 and was the final one starring Ncuti Gatwa. Its finale ended with his Doctor regenerating, followed by the surprise return of Billie Piper, who previously played Rose Tyler. BBC has not said whether Piper will become the next Doctor, saying only that how and why she returned “remains to be seen.”

Since 2023, Doctor Who had been produced by the Cardiff-based company Bad Wolf, while BBC also had a deal with Disney+ to co-produce and distribute the series internationally. Disney+ left the project in 2025 after 26 episodes, and will no longer be involved.

BBC said Doctor Who remains an important part of the corporation and that the tender process shows its continued commitment to the series.

The broadcaster said it had decided not to use a one-off special simply to fill the gap, but to focus on the show’s long-term future.

Davies, who first revived Doctor Who in 2005 and returned as showrunner in 2022, said he was excited to see what comes next.

“Will they keep the theme tune? Will they lose the blue box? Will they bring back the Drahvin?! It's all up for grabs, which is so Doctor Who, exciting and unpredictable and new! Here comes the future,” he wrote.

A previously announced animated Doctor Who series for CBeebies remains in production.
