The BBC will announce who will play the next Doctor after Matt Smith, who leaves in this year’s Christmas special, on BBC One this Sunday August 4th at 7pm – or, in Sydney time, 4am on Monday August 5th.
According to a BBC press release:
Widely regarded as one of the most hotly contested roles in British television, the show’s host Zoe Ball will unveil the 12th Doctor in the first ever interview in front of a live studio audience set against the backdrop of a swirling vortex, amongst Daleks and the TARDIS.
The show will also include some former Doctors, companions and some celebrity guests to talk about their favourite moments – basically, this is essentially a reunion clipshow special in celebration of the show’s 50th anniversary.
It will also be simulcast on BBC America in the US, though no word if the ABC plans to simulcast it.
