YA adaptation madness: trailers for 'Beautiful Creatures' and 'Mortal Instruments' arrive

With "The Twilight Saga" finally ending this very Friday with the release of the final film in the insanely popular franchise based on Stephenie Meyer's insanely popular book series, there's nothing that Hollywood wants more of than a fresh crop of supernaturally-tinge​d YA-friendly film franchises to fill the gaps. Luckily for them (and young readers everywhere), there's a whole mess of new films on the horizon that fit that bill. And, luckily for everyone even mildly interested in finding a new franchise to obsess over, we've got two brand new trailers for two brand new film properties that could be the next "Twilight" (or the next "The Hunger Games" or the next something even better). But just what are "Mortal Instruments" and just who are these "Beautiful Creatures"?

Bing: 'Beautiful Creatures' | 'The Mortal Instruments'

First up, "Beautiful Creatures"! Based on the book series by Kami Garcia and Margaret Stohl, the first film of a presumed franchise is coming to us from "P.S. I Love You" director Richard LaGravenese. It stars Alden Ehrenreich, Alice Englert, Jeremy Irons, Viola Davis, Emmy Rossum, and Emma Thompson. It is described as, shockingly, "a supernatural love story" and it centers on, honestly, as best we can tell, witches or something. What has "Beautiful Creatures" got? A stellar cast and a romantic setting. We're intrigued.

So what of "The Mortal Instruments"? The first film, "The Mortal Instruments: City of Bones" is based on Cassandra Clare's series, and is directed by "The Karate Kid" director Harald Zwart. Its cast as a touch less star power, but is still quite impressive in its depth; it includes Lily Collins, Jaime Campbell Bower, Robert Sheehan, Jemima West, Kevin Segers, Kevin Durand, Robert Maillet, Lena Headey, Jared Harris, Godfrey Gao, Aidan Turner, CCH Pounder, and Jonathan Rhys Meyers. This one is about, again, as best we can tell, demon hunters and a "hidden" world that they try to keep away from mortals. Oh, and that world includes more than just demons - it's also got warlocks, vampires, werewolves, and more. They are not messing around.
