You won’t need to hop into a TARDIS and travel back in time to catch new Doctor Who episodes featuring the fictional military organization UNIT. That also goes for Kate Stewart, who leads the group’s scientific research department.

The long-running sci-fi show confirmed actress Jemma Redgrave will return to the show as Kate, and also added that Aneurin Barnard is joining the cast.

In a “cast announcements” tweet, the official Doctor Who twitter account run by BBC wrote: “UNIT returns! Jemma Redgrave returns as Kate Lethbridge-Stewart, and UNIT, the long-running organization set on defending the Earth, returns in the next series of Doctor Who. Aneurin Barnard also joins the series as the mysterious Roger ap Gwilliam.”

No other details were released. Redgrave, 57, was first cast in the series in 2012, and has recurred in the role, including in a 50th anniversary special in 2013, episodes in 2014 and 2015, as well as in episodes from 2021, on. 

Welsh actor Barnard, 35, has previously appeared in the films Dunkirk and The Goldfinch, and will play the mysterious 21st century politician encountered by the 15th Doctor.

The new series will return later this year, with new episodes appearing on the ABC and Disney Prime. In October, it was announced that Doctor Who was moving over to Disney+ for its upcoming seasons, but it appears that this was only partially correct, and it now appears that it will be shown on both.

 Ncuti Gatwa, of the Netflix comedy-drama show Sex Education, is set to be the 15th Doctor. He’ll make history as the first black actor to hold the series’ leading role when his first episode airs somewhere around the end of this year.

I now only have one more U.N.I.T. section to go as well as a younger Lt Colonel Lethbridge-Stewart.
