Conquest of the Useless: Reflections from the Making of Fitzcarraldo (German: Die Eroberung des Nutzlosen) is a 2004 book by the German filmmaker Werner Herzog.
It is Herzog's diaries from the troubled, three years long production of the 1982 film Fitzcarraldo.
[1][2] Kirkus Reviews called the book a "valuable historical record and a strangely stylish, hypnotic literary work".
[1] Jonathan Levi of the Los Angeles Times wrote that it reveals Herzog "to be witty, compassionate, microscopically observant and -- your call -- either maniacally determined or admirably persevering".
