6. Daniel Craig
Alright, now I know we've all heard that old urban legend started by us nerds that James Bond is actually a Time Lord and that explains his intellect and his ability to change bodies (and to give Doctor Who some credit, at least they have an explanation as to why it actually happens), so let's just put this to rest and be done with it. The idea of Daniel Craig as the Doctor? Meh. It's a fun thought, like I said, considering his intellect and charm but imagine how difficult it would be to see Craig as the Doctor without thinking he's even slightly channeling 007. Then again, I always thought the Third Doctor (Jon Pertwee) was kind of secret agent-ish. If Craig could channel more of Three, it could work. But please don't, Mr. Craig. You're perfect just the way you are right now. Please just keep making more Bond films until the end of time because that's the role you were born to play, not the Doctor.
