Who would make for a good Kai?

I agree that Kai should either be played by MM or no one, BUT, if I had to, I’d say Rudolf Martin has a similarly dark, brooding, morose, yet handsome face. He guest starred as Dracula on Buffy, and also played Vlad on the USA TV movie “Dark Prince, the True Story of Dracula”. He’s not as “pretty” as MM, but he’s the closest looking to him that I’ve seen in terms of a type (basic bone structure, black hair, generally deceased appearance, still a hottie.) Hugh Jackman and Ben Affleck are too different looking from Kai/MM in my book, although Johnny Depp’s Edward Scissorhands persona is reasonably similar.Interesting question!
