Families come in all shapes and sizessometimes even in the shape of trolls dressed in crumpled cardboard boxes. In this stop-motion animated film, based on the 2005 illustrated novel Here Be Monsters!, an infant boy named Eggs (Game of Thrones' Isaac Hempstead Wright) is discovered by the boxtrolls, impish creatures who dwell below the winding streets of Cheesebridge. They adopt him and raise him as their own, and Eggs grows up never knowing that he's human. As he reaches adolescence, though, the boxtrolls are facing a major PR problem: The fromage-fixated villagers believe that they kidnap children and steal cheese by night. The villainous Archibald Snatcher (Ben Kingsley) plans to exterminate them, so Eggs turns to haughty heiress Winnie (Elle Fanning) to save his adoptive family.
