Doctor Who casts Indira Varma in mysterious Duchess role

Varma said of her new role: "I’m thrilled to be in Doctor Who and particularly excited to be crossing cosmic paths with Ncuti, as the Doctor, and look forward to creating interplanetary mischief with him. I loved playing Suzie Costello for Russell T Davies in Torchwood so am thrilled to be entering this world again."

Showrunner Russell T Davies added: "I'm overjoyed to be reunited with Indira after our Torchwood days, and this part is truly spectacular! A whole new audience will be hiding behind the settee when the Duchess unleashes her terror."

We can't wait!

Aside from Torchwood, Varma's known for her stunning performances in shows like Obsession and, of course, Game of Thrones.
