PB Casting Help

So I'm trying to decide who should play Lord Corwyn, an Unseelie Elf of creepy cunning and terrible power. He's racist as all get out and wants to rule the world. I'm stuck between
Rutger Hauer
Christopher Walken
Jason Isaacs
Alan Rickman
Christopher Lee
Peter Cushing, and just now,
Boris Karloff.

Any suggestions?

Long as I'm at it, good guy elves one of whom used to be in a biker gang and an asian girl who's got a few extra pounds on her but used to be a boxing champ.
