A new Doctor is coming to Doctor Who. This November will see the release of the first and final adventures of David Tennant's Fourteenth Doctor, who will be bowing out in the last of the sci-fi series' three 60th anniversary specials to make way for the Fifteenth Doctor, played by Ncuti Gatwa. Gatwa's Doctor will return this Christmas for his first full episode before appearing in a new series in the new year.
