Re: 50th Is "The Day Of The Doctor" (And Is 75 Minutes)
Who's the guy in the very beginning of the trailer. The first guy we see, in the constable hat?
Probably the policeman who appears in the show's very first scene, looking around Totter's Lane with his torch. Technically he's the very first character to appear on the show.
