NEW YORK — To go with "Twilight" and "The Hunger Games," Lionsgate now has a trio of young-adult franchises with the box-office leading "Divergent." The teen science-fiction thriller starring Shailene Woodley debuted with $56 million over the weekend, according to studio estimates Sunday. The opening, while less than some anticipated, launches Lionsgate's third franchise built on young-adult best-sellers. With an audience 59 percent female and half under the age of 25, "Divergent" lured young moviegoers with another film targeting teenage girls with dystopian drama and an upcoming star. "Divergent," though, fell well short of its forerunners: "Twilight" opened with $69.6 million in 2008, and "The Hunger Games" began with $152.5 million in 2012. — AP
