Gillan’s been a vocal supporter of The BBC’s decision to cast a female Doctor, even as far back as when it was first announced that Peter Capaldi would be stepping down from the role.
When asked back then, Gillan was gunning for Helen Mirren specifically, but we can speculate she’s happy enough that a woman is simply in the role now.
With four years of appearing on Doctor Who under her belt as a companion (and one episode as a Soothsayer), it’s safe to say Karen Gillan is a bit of an authority on what the character of the Doctor can and can’t do.
