New ‘Doctor Who’ star will finally be announced this Sunday (August 4)

Matt Smith's successor to be unveiled during a live 30-minute special on BBC One

The next star of Doctor Who is going to be revealed this coming Sunday (August 4).

The announcement will be made in a special live 30-minute TV show beginning at 7pm on BBC One. After the new star is unveiled, he or she will be interviewed by host Zoe Ball in front of a live studio audience.

The programme, titled Doctor Who Live: The Next Doctor, will also feature special guests including Time Lords old and new, former companions and celebrity fans of the long-running sci-fi series, a BBC press release promises. Current Doctor Who star Matt Smith and the show’s executive producer Steven Moffat will both give interviews too.

“The decision is made and the time has come to reveal who’s taking over the TARDIS. For the last of the Time Lords, the clock is striking 12,” Moffat teases in the press release.

The latest bookmakers’ odds from Paddy Power have The Thick Of It star Peter Capaldi as 7/4 favourite to succeed Matt Smith, Time Lord since 2010. Ben Daniels (Cutting It) is second favourite at 4/1, followed by Rory Kinnear (Skyfall) at 6/1 and Daniel Rigby (Eric & Ernie) at 7/1.

Smith announced in June that he will be leaving the show at the end of this year (2013). Viewers will see his Doctor regenerate during the upcoming Christmas special.

Before then, Smith’s Doctor will return in the show’s 50th anniversary special airing on November 23. In addition to current companion Jenna-Louise Coleman, he’ll be joined for the episode by his Doctor Who predecessor David Tennant and popular former companion Billie Piper.
