text: On 8 May 2022, Ncuti Gatwa was cast as the Fourteenth Doctor. David Tennant and Catherine Tate were also announced to be returning to the series in a similar set of specials airing in 2023 to commemorate the 60th anniversary of the series. Following Tennant's re-introduction to the series at the end of "The Power of the Doctor" it was revealed that Gatwa would actually be playing the Fifteenth Doctor while Tennant would hold the role of the Fourteenth. Bernard Cribbins appeared in the 2023 specials as Wilfred Mott in a posthumous role because of Cribbins death after completing filming. Langford also reprised her role once more in the final special, "The Giggle." Gatwa was first introduced in this episode, before his first full episode in the 2023 Christmas special, with the fourteenth series screening in 2024. This series is also set to see Langford make further guest appearances. In May 2024, it was revealed that Nicola Coughlan would star as the Doctor's one-off companion in the 2024 Christmas special. Gatwa and Gibson will both continue their roles into the fifteenth series, and are set to be joined by Varada Sethu, who first appeared in the episode "Boom" (2024) as an unrelated character.
