Burn! (Italian: Queimada) is a 1969 Italian drama film about the creation of a fictional banana republic in the Caribbean. The film is directed by Gillo Pontecorvo and stars Marlon Brando, Evaristo Marquez, and Renato Salvatori; its music was composed by Ennio Morricone. Brando is cast as a British agent, named after the American filibuster William Walker, who manipulates a slave revolt to serve the interests of the sugar trade. Natalie Zemon Davis reviewed the film from a historian's perspective and gave it high marks, arguing that it merges historical events that took place in Brazil, Cuba, Santo Domingo, Jamaica, and elsewhere.
