Rupert Graves has revealed a few teasers about his Doctor Who role in a recent interview with his official website.

The Sherlock actor will be appearing in Series 7 as Riddell, and described the character as “a big game hunter”. He said: “He’s in Africa, and there’s some kind of history behind him and the Doctor, although it’s never fully explained what. So he’s there to help the Doctor.” He also reveals that he’d never want to play the Doctor himself, explaining: “Once you get attached to one character, you never get peace.”

Other confirmed guests for the next series include Mark Williams and Dougray Scott.
