Political movies can approach the notion of politics and government from numerous perspectives, and with many wildly divergent purposes. Some of the earliest and best-remembered films were essentially propaganda tools being used by a political party or ideological group, hoping that the new media of cinema could be useful in helping to persuade or mollify the masses. (In some cases, as with the Nazi documentary "Triumph of the Will" or Sergei Eisenstein's massively influential "Battleship Potemkin," they were undeniable successful, at least initially.)
Political films can also serve the opposite purpose, encouraging people to distrust or even fear their government, or attacking an individual politician or political movement specifically. Some of the best political movies, the paranoia thrillers of the 1970s, for example, reflected America's distrust in its own leaders following the Watergate and other corruption scandals. More recently, George Clooney's "Good Night, and Good Luck" told a true story about journalist Edward R. Murrow facing off against Joseph McCarthy, but as a way of discussing political issues that remained relevant even upon its release in 2005. Good political movies are able to illuminate complicated situations for their viewers.
Many Americans' understanding of complex political situations, both in their homeland and in other countries, as well, comes from watching popular films. For example, the satirical take on the politics of war in "Wag the Dog," the insights into Greek politics provided by Costa-Gavras "Z" or the look at Bolivian elections in the documentary "Our Brand is Crisis."
