We’ve known for a little while that The Doctor’s next companion has been cast. Now, the BBC has officially revealed who it is: Pearl Mackie.
The BBC made the announcement with a short scene from the upcoming season, introducing Mackie as Bill:
Mackie’s CV is light, currently performing in The Curious Incident of the Dog in the Night-Time for the National Theatre, and has appeared on Doctors, and in 2013's Svengali.
Let’s hope that the show puts her to better use than Clara.
