I just got the news that David Tennant is leaving Doctor Who at the end of 2009, see the news from the BBC. Unfortunately, if you are outside the UK the interview cannot be seen from the BBC website. Possibly it is out there on U-Tube, but I have not investigated.
We will still see Tennant in the Christmas Special this year and in 4 specials in 2009. Interesting enough the title of the Christmas special will be “The Next Doctor”. Could this be an indication of things to come ?
2010 will see a new showrunner, Steven Moffatt, along with the 11th (or is it 12th after the “funny” regeneration last season?) Doctor.
It will be interesting to see who will be cast as the 11th Doctor. Your guess is as good as mine. The rumour mill has probably already started.
I will have to say that I really liked Tennant as The Doctor. This autumn/fall he has been playing Hamlet with Patrick Stewart in the UK. Stewart has said that he is interested in being in Doctor Who, it could be interesting to see him as a villain for a change. Could he become the 11th Doctor ? Possibly, but I doubt it. It could be interesting, though.
