It is said in RTDs book that they (the BBC) were not allowed to lie. Yes they can be economical with the facts but actually saying the complete opposite to what they plan to do is lying...and according to RTD the BBC cannot do that to the british public...or anyone else for that matter.

Benedict Cumberbatch would have to be favourite to take over if Smith leaves:

Interesting quote from Mr Moffat in this BBC news article...

http://www.bbc.co.uk/news/entertainment-arts-10725501

Wouldn't Benedict Cumberbatch make an ideal Doctor Who?

"There is no vacancy," said Moffat. "Matt Smith is the Doctor and he's been an astonishing success and - who knows - maybe he'll never regenerate again."

matt smith isn't leaveing

SHAME

I hope he stays the full five possible years of his contract.

Me too, he's fantastic in the role

The press will often fire questions at actors just to see what response they get.

An actors best option is usally to say nothing, the tv company involved will take care of press releases and the press know that. But they can't resist poking around hoping to get an exclusive bit of info.
