The Doctor Who season 14 cast features a group of exciting actors and actresses to advance this classic sci-fi show into a new age. Following the departure of Jodie Whittaker as the thirteenth incarnation of the titular time-traveler, the show’s fourteenth season is a completely fresh story with new characters and new adventures as a new version of the Doctor takes the reins. It’s a trademark of the show for the Doctor to change their face every few years, and season 14 marks the beginning of the Fifteenth Doctor’s tenure.

Following Jodie Whittaker’s brilliant regeneration scene, Doctor Who offered the shock twist that David Tennant would be reprising the role of the Doctor for the 60th-anniversary specials in 2023. Although his return was an extremely exciting moment for the show’s dedicated fanbase, season 14 is a completely fresh start with a cast of characters that audiences have never seen before. However, Doctor Who also brought back Russell T Davies as the season’s showrunner, suggesting a subtle return to the writing and atmosphere that made the show’s early episodes so beloved. Here's a guide to the new and returning cast, the characters they play, and what else they're known for.

Ncuti Gatwa As The Fifteenth Doctor

Ncuti Gatwa as the Fifteenth Doctor in Doctor Who

Sex Education actor Ncuti Gatwa plays the Fifteenth Doctor in the Doctor Who season 14 cast. The Doctor has always been the centerpiece of Doctor Who, and while the character has taken several faces throughout their many lives, they’ve always dedicated themselves to protecting the universe and saving the lives of those in need. That’s what makes them such a compelling protagonist, and Gatwa’s incarnation will undoubtedly be no different.

Gatwa’s most popular role before Doctor Who was Eric Effiong in Netflix’s Sex Education, a serial comedy that gathered plenty of acclaim and popularity for its mature writing and relatable themes of sex, adolescence, and the complexities of early relationships. Though Gatwa doesn’t have too many projects under his belt, he’s been praised for everything he’s done. The actor received three BAFTA nominations for playing Eric Effiong, and it’s this acclaim that led to his casting in Doctor Who. Gatwa also stars in Greta Gerwig’s Barbie, a subversive comedy about the titular toy’s adventures through the human world.

She was even crowned Queen of Queens in the show’s All Stars season, facing off against other drag queens that have found success on the show.
