A while back, I mentioned that John Hurt would be a really good choice to play the ancient Founder named Indurane in David R. George III's Olympus Descending, from the third volume of Worlds Of Deep Space Nine. John Hurt is an incredibly versatile actor. He can play characters that are vulnerable and/or eccentric (Alien, The Elephant Man, The Naked Civil Servant, 1984). But as anyone who's seen his recent performance in V For Vendetta knows, he can also project an air of threat and menace. In my opinion, that's just the exact combination of qualities you need if you're casting for an elderly changeling!
