Inspired byoPink Floyd's album of the same name, Pink Floyd: The Wall is a dark, expressionistic musical, told from the point of view of Pink, a depressed rock musician. The film is structured around Pink's reflections on his life, all of which center on the building of "the wall". This wall is a metaphor for psychological isolation, a barrier Pink creates to distance himself from his pain. Director Alan Parker approaches this material in a highly stylized manner, mingling animation and dream-like sequences to suggest Pink's perception of the world. These techniques complement the almost constant music, which the film often uses in place of dialogue.
