In 24 hours we'll know who the new Who is...

This Saturday night at 5:35pm (UK time) the BBC will announce the name of the actor who is to play the latest incarnation of our favourite Time Lord on Doctor Who, once the character regenerates later this year with the departure of David Tennant from the role.

In a special edition of Doctor Who Confidential (the behind-the-scenes program which usually details the makings-of the long-running TV program) entitled The Eleventh Doctor - retitled from The Ten Doctors only a few hours ago - the BBC will look at the various actors to have played the role since the program's inception in 1963, and now promise that:

The name of the actor who will replace David Tennant in Doctor Who will be announced on Saturday.

Tennant said in October that he would stand down from the show after filming four special episodes in 2009.

His replacement - the eleventh Doctor of the TV series - will be revealed in a Doctor Who Confidential programme on BBC One at 17:35 on 3 January.

The casting was confirmed over Christmas and filming for the 2010 series begins in the summer.
