If I had done this feature days after the last Harry Potter film, Daniel Radcliffe would not be on this list at all. But late 2012 saw him starring in a small seen miniseries for Sky Living called "A Young Doctor's Notebook". Not only was it a nice four parter with a general charm attached to it, but it highlighted the unseen comedic skills that Daniel had developed during Harry Potter. Granted, there was a hint of that skill in the sixth installment Harry Potter And The Half Blood Prince. But in Young Doctors Notebook, it was more impressive, and more funny. So that being said, I think Radcliffe would be an interesting choice for The Doctor, purely for the fact that he has the charisma and experience of taking on a high profile role and delivering on screen. I also feel Radcliffe could model his own unique look and personality to The Doctor which may mirror similarly to Matt Smith's 11th Doctor or maybe even Peter Davidosn's 5th Doctor.
