The BBC has confirmed that both David Tennant and Catherine Tate will be returning to Doctor Who to help mark the show's 60th Anniversary.
The Tenth Doctor, as played by Tennant, was paired with Donna Noble, played by Tate, in Series 4 of Doctor Who shown in 2008.
Often described as one of the most loved pairings in Doctor Who’s history, the two have reunited and are filming scenes that are due to air in 2023 to coincide with the show’s Dimond Jubilee celebrations.
The Doctor and Donna parted ways when the Doctor had to wipe Donna's memory, making her forget him, in order to save her life. He left her family with a warning: if ever she remembers, she will die. But with the two coming face to face once more, the big question is, just what brings the Doctor and Donna back together?
Russell T Davies, Incoming Showrunner says:
They're back! And it looks impossible - first, we announce a new Doctor, and then an old Doctor, along with the wonderful Donna, what on earth is happening? Maybe this is a missing story. Or a parallel world. Or a dream, or a trick, or a flashback. The only thing I can confirm is that it’s going to be spectacular, as two of our greatest stars reunite for the battle of a lifetime.
Tennant left the series in 2010 but returned for the 50th Anniversary story The Day of The Doctor.
