The DUFF is an upcoming film coming in 2015.
Story follows Bianca (Whitman), a high school senior whose world is turned upside down when she discovers she's been labeled her social group's DUFF (designated ugly fat friend), a sidekick of sorts to her prettier, more popular friends. She becomes determined to reinvent herself, enlisting her fellow DUFFs in a scheme to overthrow Madison, the school's evil queen.
Thorne is in negotiations to play Madison, who will do everything in her power to keep Bianca in her place as a DUFF.
McG and Mary Viola are producing for Wonderland Sound and Vision along with Vast Entertainment's Lane Shefter Bishop, who brought the book to Wonderland. CBS Films boarded the project in 2011, and its executives Mark Ross and Alex Ginno will oversee the project on behalf of the studio.
