1st official pic of David Bradley as the 1st Doctor in Who 50th special

The BBC has released the first official still of actor David Bradley (Harry Potter) as William Hartnell playing the First Doctor from the Doctor Who 50th docudrama special An Adventure in Space and Time.

David Bradley—mostly known to the general U.S audiences as that b@$**rd Walder Frey on Game of Thrones—is portraying actor William Hartnell, who played the First Doctor on Doctor Who in the upcoming BBC Two drama.

Writer Mark Gatiss said: “David Bradley brings every ounce of his talent, humour and presence to the role of William Hartnell. It’s a wonderfully touching and subtle performance and I’m immensely proud of both him and the film.”

Actor Reece Shearsmith, who plays Patrick Troughton, who was Doctor Who’s Second Doctor, said that Bradley is "absolutely brilliant" in the docudrama. "[Mark has] done a really good rendering of that time and that story. I think it's a real treat."

An Adventure in Space and Time recounts the beginnings of Doctor Who, which first aired on Nov. 23, 1963.

Actor Brian Cox (The Bourne Identity) plays the BBC's head of drama, Sydney Newman—who was often attributed with the creation of the show—while actress Jessica Raine (Call the Midwife) will play legendary BBC producer Verity Lambert.
