David Tennant has admitted that he is jealous of Matt Smith, who is just beginning his Doctor Who journey.

Tennant recently filmed his last scenes as The Doctor and Matt Smith has already began filming for the new series of the BBC sci-fi show.

Tennant told BBC Newsbeat: “I’m really excited for him but I remember how exciting it was starting out on this kind of a journey – and nervewracking and a bit overwhelming but just such a kick.

“So I’m jealous he’s going through that now, but [it's] brilliant and it couldn’t happen to a nicer chap.”

He added: “I’m sure it’ll be a bit odd at first to watch somebody else playing the part but I’m really looking forward to not knowing what happens next as well.

“I’m looking forward to being a viewer again because I’ve always loved Doctor Who so I can’t wait to sit down and watch a new one.”

Tennant joked: “I do think it’s a bit like being President of the United States, I think you always get to be called the Doctor. I will always expect, when I see you in the future, to refer to me as the Doctor, clearly.”
