The built-in turnover of Doctor Who keeps the Regeneration rumor mill in perpetual motion, and it seems Peter Capaldi is finally turning that wheel. The BBC confirms Capaldi will exit the role in 2017, kicking off the search for a 13th (technically 14th) Doctor.

As confirmed over Twitter, Capaldi will leave Doctor Who behind as of the 2017 Christmas special. The actor had previously stated his intent to work through the entirety of Season 10, while it remains unclear if Pearl Mackie’s new companion Bill will be staying on for a new Doctor.

Elsewhere, in addition to Michelle Gomez’s likely return as Missy, Season 10 will also feature Jekyll & Hyde star Stephanie Hyam in a minor role. Pearl Mackie will also joined in the role of new companion Bill, while Peter Capaldi has suggested Jenna Coleman’s Clara might return in some form.

Steven Moffat’s last season was also confirmed for spring 2017, placing Chris Chibnall as the new head writer and executive producer, to begin after Season 10.

We’ll see more soon, but check out the first Season 10 trailer below, and stay tuned.
