Jemma Redgrave who appeared as Kate Stewart, the late Brigadier’s daughter, in The Power Of Three has said that she's defintely up for returning to the show.
Asked about coming back for another UNIT story, she told Doctor Who Magazine: “I should be so lucky! I’d be so privileged. I keep using that word. I should use a different word. But I do feel that. It’d be great to come back. Yes, I’d love that.”
She added: “You look at the phenomenal actors that they get on this show, the calibre of talent that they get, and you think, ‘Gosh, if I’m part of that tradition, I must have done something right at some point in my career.’”
Would you like to see Kate return?
