In the last installment of Christopher Nolan's Batman film trilogy, the villain Bain and his adjutants hold Gotham's economic elites to account for their various crimes against the less fortunate. In "Elysium" and "Snowpiercer," the hoi polloi organize revolutions to overthrow their occupiers and oppressors. In "Divergent" and the wildly popular "Hunger Games" movies, children from different socioeconomic strata battle each other to the death for the entertainment of their bettors. (Despite coming from the lower castes, Katniss Everdeen, the "Hunger Games'" female teen protagonist played by Oscar-winner Jennifer Lawrence, of course impresses with her unusual wit and wiles.)
