Buddha Bless America 太平天國 (1996), directed by Wu Nien-jen 吳念真, represents the disruptions and complexities of a postcolonialism as well as any film I am aware of.
The film is set in Taiwan during the Cold War during the 1960s, and it focuses on a local community of residents who are relocated to a small elementary school while the United States and Nationalist armies jointly conduct military exercises on the community's farmland.
The story traces the impact of this event on the lives of a middle-aged man named Lin who initially supports the intervention, but over time becomes disillusioned while retaining a positive overall image of the U.S. At the same time, his son is removed from his regular school routine and hangs out with his friends day and night -- they watch the U.S. military exercises and observe the behavior of men at a brothel built specifically for the foreign troops; meanwhile, his grandmother strives to maintain her family's dignity while her fading memory leads her to blur the lines between concurrent events and events that occurred previously during Japanese colonization.
In a memorable scene she stands her ground and uses a wooden broom to prevent U.S. tanks from ruining her farm property.
The way the film presents a type of psychological colonization on the local populace is effectively conveyed throughout the film by the stylistic use of music and the passage of time -- in another powerful scene, slow-motion is used to portray a grandmother and then a boy walk in front of the camera while a light bulb sways in the foreground and men fight in the background -- leaving a lasting impression.
