Behind the scenes
- Like the War and Ninth Doctors, the Twelfth Doctor unusually debuted on television before his regeneration from his predecessor was screened.
Trivia
- His first words as The Doctor keep to the modern tradition of new Doctor's commenting on their bodies (e.g. the Tenth Doctor's first words were "New teeth. That's weird" and the Eleventh Doctor's first words were "Legs. I've still got legs."). The Twelfth Doctor first words were "Kidneys! I've got new kidneys!".
