1. Tom Hiddleston

I know the world is Tom Hiddleston mad at the moment, but for real. He is Morpheus.

2. Ben Whishaw

He's very talented and can definitely play "thin, pale and creepy."

3. Sacha Baron Cohen

A surprisingly good "straight man" when he wants to be, though physically less the "type" than the first two. I can still see him pulling this off, possibly with better aggression than Whishaw.

4&5. Either of The Goth Detectives

Admittedly, more for the spoof version. But still.
