Jennifer Lawrence is transitioning back into Katniss Everdeen! The Hunger Games actress (in Elie Saab) made a quick stop at the Toronto International Film Festival today to promote Silver Linings Playbook—her new movie with Bradley Cooper—where she debuted her deep chocolate Katniss Everdeen hue. This is the last weekend she'll be in JL mode before fully becoming Katniss--the whole Games crew starts filming the sequel, Catching Fire, come Monday.
