4. Ralph Fiennes
I don't really need to write anything here. Just by reading or hearing his name you think, "YES!" And I'm not talking about him only as the Master. If they said Ralph Fiennes was cast as Rainbow Dash in the live action My Little Pony film you'd think, "SHUT UP AND TAKE MY MONEY!" Whatever role he takes on, he truly takes on. And he's made a great name for himself playing bad guys. From the serious, academy award worthy performances in things like Schindler's List to the campy and stereotypical like Voldemort and Hades, he's always the best thing on screen. (His character in Red Dragon is a personal favorite. Thanks for peaking there Brett Ratner.) So why not the Master? He's always seemed an actor who likes to do whatever he wants whenever he wants to. His body of work is extensive and eclectic, and, based on early reviews, he's very funny in Wes Anderson's latest, The Grand Budapest Hotel. He is truly and actor's actor, someone anyone in the profession should admire and hope one day to have a career resembling even a shred of his. Given that he seems pretty open to all projects without discrimination, a few episodes on Doctor Who could be right up his alley.
