Vidanric!! Oh, wait, he's not real...

(he's from "Crown Duel" by Sherwood Smith in case anyone is interested. Excellent book!!)
Aww, can we add fictional characters? I mean, I know there are many anime ones, but at least they have pictures... I'll just add one more. Anyone read Tomara Pierce's books (really, really, really good!! Well, the Tortallan ones anyway...)? In Keladry's books there's Joren, an evil git who's vain with good reason, blonde, and well-respected by other evil gits. Not that Draco is
really an evil git, he just appears to be one in the books. But we know that deep down he's a big softie!

Okay, maybe not softie, but he's good.
See
here for a gorgeous sketch of Draco. That may not strictly count as a "look-a-like", but I suspect the artist uses photographs as guides (that or she has a damn good imagination *drool*), so there must be someone who looks like that somewhere out there.
