Walker (1987)

A hallucinatory biopic that breaks all cinematic conventions, Walker, from British director Alex Cox (Repo Man, Sid & Nancy), tells the story of nineteenth-century American adventurer William Walker (Ed Harris), who abandoned a series of careers in law, politics, journalism, and medicine to become a soldier of fortune, and for several years dictator of Nicaragua. Made with mad abandon and political acuity - and the support of the Sandinista army and government during the Contra war - the film uses this true tale as a satirical attack on American ultrapatriotism and a freewheeling condemnation of "manifest destiny." Featuring a powerful score by Joe Strummer and a performance of intense, repressed rage by Harris, Walker remains one of Cox's most daring works.
