Davies makes plans for fourth 'Dr Who' series

Doctor Who writer Russell T Davies is already making plans for a fourth series of the show.

Although the cast and crew are currently working on series three, Davies is looking to the future and has been dreaming up adventures to air in 2008.

"I would absolutely love to do a fourth series. We're waiting for the nod and we're fairly confident it will come," Davies told Doctor Who magazine.

"The producer [Phil Collinson] and I drove up to Manchester the other day and in the space of that car journey we already had nine episodes."
