Some of our favourite Doctor Who characters are said to be returning to the show for David Tennant’s last appearance as the timelord.

The Sun reports that Billie Piper, who played Rose Tyler, Freema Agyeman, who played Martha Jones and Catherine Tate, who played Donna Noble will join forces to take on the Doctor’s arch rival The Master (John Simm) in the epsiode which shows David Tennant regenerate into Matt Smith.

“This will be the most exciting episode Doctor Who have ever done,” an insider said. “Getting Billie to agree is a real coup, but she loved working on the show so much it didn’t take much convincing,” they continued.

Our very own blogger Gerard isn’t so convinced about the comebacks though. On his Unreality Shout blog he says:

To be honest, I’d rather they didn’t bend the universe out of shape just to bring back the three companions. Martha Jones, maybe. Just to ease the transition. But no more Rose and her new accent. And why drag Donna back into it after going to all the bother of wiping her mind?
