8. Idris Elba
Because why not? Even if you've only seen ten minutes of Luther you know tha Idris Elba is a forced to be reckoned with. I mean, he cancelled the apocalypse for God's sake. If he can do that, surely he could change his mind and play a character who brings about the end of days instead. As mentioned up top, the wishlist of who SHOULD play the Master could go on forever. And it fills me with a lot of girlish "SQUEE!" to think of Elba going toe to toe with all of space and time's greatest hero. As an actor he's incredibly intense and very, very powerful. Any frame of film (or frame of...digital?) containing him just vibrates with awesomeness. It's impossible to take your eyes off of him. And since he's been playing good guys for the past several years, and recently the ultimate good guy as Nelson Mandela, why not change things up and play a bad guy? That's what all actors do when they're afraid of being typecast right? They play crazy people! "See? I'm not one note. I can do bad all by myself!" (A Film by Tyler Perry) What's so impossible about a currently in demand movie star making the move back to TV when he's probably worked so hard to get out of it? Exactly. But in the immortal words of the Andrew's Sisters, "I can dream, can't I?"
