Speaking of Ncuti’s departure, Russell T Davies, Showrunner said: "What a Doctor! Thank you, Ncuti! As his final words say, this has been an absolute joy, and the team in Cardiff and everyone who has worked on this show for the past few years, are so lucky to have been part of Ncuti’s great adventure as he shoots off to stratospheric new heights."

Ncuti Gatwa has left the sci-fi series, "Doctor Who," after two seasons and former franchise co-star Billie Piper is taking his place.

After 2 seasons as the Fifteenth Doctor, Ncuti Gatwa is leaving the TARDIS behind, seemingly handing over the keys to a familiar face in Billie Piper.
