According to the official announcement by the BBC, 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 decision is made and the time has come to reveal who’s taking over the Tardis,” Moffat said.
“For the last of the Time Lords, the clock is striking twelve.”
Star of The Thick of It Peter Capaldi is currently favourite with many bookies. Others in the running include stage and screen stars Daniel Rigby, Rory Kinnear and Ben Daniels.
