Speaking to BBC News, Mr Tennant said, “It was very emotional saying cheerio, There’s lots of scenes in the final episode that are very sad, and were very sad to play. On the actual final day I was a bit of a puddle, but kept a mildly stiff upper lip.”
The actor admitted that he was nervous, inviting another Doctor into the TARDIS.
“I’m thrilled that it’s carrying on, and know that everyone who’s there is a great choice, but of course you feel a bit proprietorial.”
Speaking of The Waters Of Mars, David said, “It tells a different sort of story. We expect the Doctor to take control earlier,” he said.
Former Executive Producer, Russell T Davies added, “It’s not so scary as intense”.
Don’t forget that Doctor Who: The Waters Of Mars is set to broadcast on Sunday 15th November 2009 at 7:00PM on BBC One.
