The Great Gilly Hopkins. A feisty foster kid’s outrageous scheme to be reunited with her birth mother has unintended consequences in The Great Gilly Hopkins, an entertaining film for the entire family. Gilly Hopkins (Sophie Nélisse) has seen more than her share of foster homes and has outwitted every family she has lived with. In an effort to escape her new foster mother Maime Trotter’s (Kathy Bates) endless loving care, Gilly concocts a plan that she believes will bring her mother running to her rescue. But when the ploy blows up in Gilly’s face it threatens to ruin the only chance she’s ever had to be part of a real family. Based on the award-winning young-adult novel by Katherine Paterson (Bridge to Terabithia), The Great Gilly Hopkins stars Sophie Nélisse, Kathy Bates, Julia Stiles, Bill Cobbs, Billy Magnussen, with Octavia Spencer and Glenn Close.
