Doctor Who: Flux - 15 Huge Details We Just Learned About Series 13

4. Dan Starkey Returns As A Sontaran

Dan Starkey has played the Sontarans for over a decade at this point, so who better to don the makeup for their grand return in Series 13?

The actor is set to appear in episode two - and possibly other episodes - as a Sontaran called Svild, presumably a member of the Sontaran army that partakes in the Crimean War.

This means that Starkey has played a Sontaran under every NuWho showrunner, including roles in The Sontaran Stratagem/The Poison Sky, The End Of Time, and A Good Man Goes To War, the episode in which he first debuted as recurring character Strax.

Elsewhere, Starkey also played one of Santa's elves in Last Christmas. Talk about versatility.
