David Bradley(IV)

One of three actors to play a supporting character on Doctor Who (2005) then go on to play The Doctor. He played Solomon in Dinosaurs on a Spaceship (2012) then played William Hartnell, the First Doctor in Una aventura en el espacio y el tiempo (2013). The other two were Colin Baker in "Arc of Infinity" then the Sixth Doctor and Peter Capaldi in The Fires of Pompeii (2008) and then the Twelfth Doctor.

[on starring in Una aventura en el espacio y el tiempo (2013)] When he asked if I would be interested, I almost bit his hand off! Mark [Mark Gatiss] has written such a wonderful script not only about the birth of a cultural phenomenon, but a moment in television's history. William Hartnell was one of the finest character actors of our time and as a fan I want to make sure that I do him justice. I'm so looking forward to getting started.
