Walt Disney Pictures has released the new trailer for Studio Ghibli's The Secret World of Arrietty, an adaptation of Mary Norton's children's book series "The Borrowers." In the film, opening in North America on February 17, Arrietty (Bridgit Mendler), a tiny, but tenacious 14-year-old, lives with her parents (Will Arnett and Amy Poehler) in the recesses of a suburban garden home, unbeknownst to the homeowner and her housekeeper (Carol Burnett). Like all little people, Arrietty (AIR-ee-ett-ee) remains hidden from view, except during occasional covert ventures beyond the floorboards to "borrow" scrap supplies like sugar cubes from her human hosts. But when 12-year-old Shawn (David Henrie), a human boy who comes to stay in the home, discovers his mysterious housemate one evening, a secret friendship blossoms. If discovered, their relationship could drive Arrietty's family from the home and straight into danger.
