Based on influential 1958 American political novel, “The Ugly American” (1963) is a realistic film, a political drama/thriller featuring Marlon Brando as a new American diplomat in a Vietnam-like Southeast Asian nation that is painfully struggling between capitalist & communist factions. Eiji Okada plays the country's revolutionary leader, a previous best-friend of MacWhite (Brando) who may be brainwashed by the communists. The ending cleverly shows how the average American is unconcerned with the political conflicts of distant nations.
