Desperate Twilight lovers may or may not be mollified by this follow-up effort based on a different series by author Stephenie Meyer. Instead of supernatural romance, it's sci-fi romance. In the near future, Earth has been taken over by parasitic aliens who need humans to inhabit. Naturally there's a love triangle between a "special" alien girl (Saoirse Ronan, The Lovely Bones) and a couple of rebellious, well-coiffed teens (Jake Abel from Percy Jackson & The Olympians and Max Irons from Red Riding Hood). Director Andrew Niccol (Gattaca, The Truman Show) shot it here in New Mexico. 125 minutes PG-13.
