10. George Clooney
Why ? Because he's George Clooney, that's why. One of the most attractive and iconic of Hollywood film stars in recent memory, and taking on the role of The Doctor would be nothing short of a must-see. However, one must speculate and debate as to what type of personality his Doctor would inhabit. Clooney could be capable of both serious and comedic, given that he has done serious films such as The American & The Ides Of Marsh, as well as the wacky and slapstick in Burn After Reading. It would be intriguing to watch and see what type of Time Lord Clooney could create, and whether he could redefine the role for new audiences to embrace. It would be interesting to watch, that's for sure.
