A24's latest film, Civil War, has been generating controversy for its use of real-life footage. The movie takes place in a future America torn apart by civil war, where the states have fractured into different factions. Among them are the revolutionary Western Forces, including California and Texas, who want to secede from the country and assassinate the authoritarian President. They are up against the Loyalist States, commanded by the President himself, now in a third stolen term in office. Civil War, which has gotten divisive reviews, stars Kirsten Dunst, Cailee Spaeny, Wagner Moura, and Stephen McKinley Henderson as four journalists covering the events.
