I think the likelihood of female Dr. Who is very unlikely.
The source of most of the rumors that a female Dr. Who is possible seems to come from a press conference that Tom Baker held when left the role, where he wished well whomever it was well, whomever he or SHE may be.
That slip of the tongue has fueled the rumor of female Dr. Who ever since.
It seems to me that British actors will do most any role. I would love to see Dench in the role. She could really take off.
Jack Davenport could probably do a fairly good Peter Davison-ish Doctor.
How cool would it be to go for someone really out there. Derek Jacobi as Dr. Who? He's done plenty of BBC work over the years.
Dude. Richard Coyle is the one true Doctor.
Dr. Who should be someone who inspires affection and trust, not someone who inspires one to fire bullets into the TV screen in the hope that at least some will be conducted to the actor himself.
I love Richard E. Grant! Don't be a Grant-er hater!
Sorry, but he seems to have made it his life's work to inject a contemptuous disregard of others into every role he's cast in, to the point that I can't separate the actor from his characters. He's preceeded only by Pauly Shore and Carrot Top on my "Get the fuck off my TV screen!" list.
Ooh, Richard Coyle as the Doctor -- that would be fun.
