Katniss Everdeen (Jennifer Lawrence) becomes the face of the revolution in the second TV spot for The Hunger Games: Mockingjay Part 1, following the first spot and soundtrack details that were released yesterday.Katniss is seen with her younger sister Primrose (Willow Shields), who reveals she is good at keeping secrets, while Plutarch Heavensbee (Philip Seymour Hoffman) tells District 13 president Alma Coin (Julianne Moore) that Katniss is the "face of the revolution." We also get a brief glimpse at Elizabeth Banks' Effie Trinket, who has discarded her normally colorful and glamorous look for a more utilitarian wardrobe, and Josh Hutcherson's Peeta Mellark spouting propaganda from the Capitol.
