Gelflings, Skeksis, and Steven King

A Dark Crystal sequel is due out in 2007. Entitled Power of the Dark Crystal, it will be directed by Genndy Tartakovsky, who directed the Star Wars: Clone Wars animated TV series (which, by the way, is better than episodes 1-3, if you ask me).

Interestingly, Wikipedia states that "[Tartakovsky] has also been pitching a cartoon series of Stephen King's The Dark Tower to HBO." More wild and breathless speculation here: aintitcoolnews.com; and here TheDarkTower.net.
