Top sci-fi series Doctor Who is exploding back onto our screens on Saturday, with 13 new episodes.
In the Time Lord's fourth series since he returned in 2005, David Tennant will once again play The Doctor. Wonder what he's up to here....?
But this time he'll be teaming up again with mouthy Donna, played by Catherine Tate.
The pair first met in the 2006 Christmas special, The Runaway Bride. The Doctor asked her to travel with him, but she said no. We assume she's now changed her mind..
And from the first episode there's loads to look forward to, from new characters and unusual monsters, to the return of some old friends. Oooh!
