Who Am I?

David Tennant explains the nature of new role to DWM.
"Playing the same character every week in a long-running series is great, and very inspiring and exciting," David Tennant reveals in the new issue of Doctor Who Magazine.
"But it's such an unexpected bonus to be asked to portray a whole new character, halfway through the shoot, which by definition must be unlike the character you're playing every other day."
So who, exactly, is this John Smith character, asks the mag?
"He looks like the Doctor and doesn't sound much like him, but he must be a different man, says David cryptically. "Well, he must be a man, rather than a Time Lord..."
DWM also catch up with guest star Jessica Hynes, writer Paul Cornell, and Russell T Davies about this very different - and even more terrifying than usual! - Doctor Who adventure...
DWM will also reveal who'll be scripting Series Four, chatting to Mark Gatiss, Steven Moffat and director James Strong and giving us 42 fantastic facts about 42!
Meanwhile, Russell T Davies will be flying the flag (for Who) in Production Notes...
