So I saw an interview with Steven Moffat where they asked him about the possibility of a FEMALE Doctor in the future. He answered that he had been thinking about it, and it is possible that they can pull that off in the future, the only thing holding them back now is the storyline. It would be pretty weird since he's married and him being male and attractive is a part of the fun.
My views on this is that it would be a brilliant idea BUT considering he's married to River Song it would be a little bit off. The fact that River Song keeps popping in and out I think makes this a little more possible, and the fact that we all know she's going to die at some point. Or "be saved" as one could call it.
If they however decide that they want a female Doctor in the future, I'm excited to see who it will be.. I don't think they would go on and pick the most known actress out there, maybe there is a woman lurking in the shadows somewhere.
What are your views on this? (:
