The BBC Doctor Who website have confirmed that Jemma Redgrave, who previously appeared inDoctor Who as Kate Stewart (Daughter of Brigadier Lethbridge-Stewart), will be reprising her role for the 50th Anniversary Special.
The BBC said:
“Jemma is part of a brilliant cast that is already known to include Matt Smith and Jenna-Louise Coleman who are joined by the returning David Tennant and Billie Piper plus screen legend John Hurt and Joanna Page. Filming is underway on the special which will be a 3D spectacular shown later this year.”
So this means UNIT are involved in some form in the anniversary episode. And its nice to know that, with Nicholas Courtney no longer with us, there will be a nod to The Brigadiers legacy with the appearance of Redgraves character in the 50th episode.
More casting announcements are expected shortly…
