5. Daniel Radcliffe
Shown above in his role as Arthur Kipps in the film The Woman in Black, Daniel Radcliffe is a strong candidate for the role of The Doctor. The BBC have made the Doctor younger than ever and Daniel is more than seven years younger than the current incumbent Matt Smith. Beyond that the Harry Potter films gave Daniel plenty of experience in dealing with the mysterious and the supernatural and his familiarity with a magic wand would come in handy when wielding a sonic screwdriver. Given as well how many years the Potter films took to make, Daniel could be the next Doctor for several years to come.
