Richard Armitage. Oy vey.
I just recently re-watched "North and South," a BBC miniseries based on the book of the same name by Elizabeth Gaskell. The first time I watched it was when I was in England--these days, I own it on DVD.
To prove his awesome sexiness, and how awesome and swoon-worthy this movie is, let me present the last few minutes, courtesy of YouTube.
If that doesn't convince you, let me provide some stills of the guy (one from "North and South," the rest from other places).
