Awesome!  Lots more fun Doctor Who to come!!!!!

Doctor Who will return for a fourth series in 2008, executive producer and writer Russell T Davies has confirmed.

Speaking at the premiere of the third series in London, Davies said: "Series four is officially existing. I’m very excited, but we have known for ages."

But he refused to say whether the star of the hit sci-fi show, David Tennant, would return in the lead role.

The third series, which co-stars Freema Agyeman as new assistant Martha Jones, starts on BBC One on 31 March.

Her character replaces former assistant Rose Tyler, who was written out at the end of the second series after Billie Piper decided to leave the show.
