Yahoo Movies just debuted three new theme-specific posters for one of three major young-adult literature adaptations dropping this year. The clear advantage that it has over Beautiful Creatures and The Mortal Instruments: City of Bones is that it's based of course on book written by Stephanie Meyer, she of Twilight fame. Saoirse Ronan is the real deal, William Hurt always has my attention, and Andrew Niccol seems an uncommonly good match for the material. This could be Open Road's shot at the big time, the same way Twilight elevated Summit Entertainment just a couple years into its existence. Anyway, The Host debuts on March 29, 2013. As always, we'll see. For those who care, a synopsis is after the jump.Scott Mendelson
