'Dr Who' boss discusses new companions

Doctor Who showrunner Russell T. Davies has dropped a few hints about the Time Lord's sidekicks in the 2009 adventures.

"What everyone’s missing is that there will be a new companion," Davies told The Times, referring to the intense speculation about David Tennant's successor.

"We’ve got a young female companion at Easter, and then a much older woman next Christmas - someone in her fifties or sixties. I love that."

Davies also revealed that he has to be careful about the actresses he uses in case it disadvantages his replacement Steven Moffat.

"It’s made casting next year’s four specials difficult because we’re going, 'Well, that’s an interesting actress, but they might want her for series five’," he said. "We don’t want to ruin anyone’s chances of being the new companion by casting her for a one-off."
