In the new Hulu original series, "Light as a Feather," an innocent game of “Light as a Feather, Stiff as a Board” goes wrong when the five teen girls who played start dying off in the exact way that was predicted, forcing the survivors to figure out why they’re being targeted – and whether the evil force hunting them down is one of their own. Star Peyton List joined BUILD to chat all about the new series as well her role in the new CBS series, "Happy Together," and her clothing line.
