Jemma Redgrave joins the Doctor Who 50th Anniversary cast
Jemma Redgrave is returning to Doctor Who for the 50th Anniversary. She'll be reprising the role of Kate Stewart - the daughter of Brigadier Lethbridge-Stewart, played by the late Nicholas Courtney. Redgrave previously appeared in last year's The Power of Three.
Redgrave bolsters the roster of returning cast which also includes David Tennant, Billie Piper and Alex Kingston and new guest stars John Hurt and Joanna Page. We know the Zygons will be making an on-screen appearance, the first since 1975 (although they were most recently referenced in the previously mentioned Power of Three).
Rumours over the last few days seem to rule out the return of Christopher Eccleston, who having met with show runner Stephen Moffat decided not to take part in the celebratory episode.
