There are a few characters, both in film and literature, that just stick around. Some are like Dumbledore, physical and emotional embodiments of the words on the page that are strong and fixed in my mind. Others are more ambiguous, they're a pervasive reminder of an emotion that was evoked when I read the book or watched the film. Randall Flagg, the dark man, is one such character. If you've read Stephen King's phenomenal book The Stand you'll know what I mean. If you haven't, well, it might be hard to explain. Randall Flagg may have a corporeal form but he's far more insidious than that. He's like black smoke, a chill on the wind, the shadows that stir in your bedroom. He's everything you fear and hate and despair of. He's terrifying and one of the single most evocative characters I've ever read. These artists have done amazings jobs capturing the darkness and shiftiness of his character, be sure to check out the full size pictures at the link, as well as the rest of their work.
