All of the actors spoke their dialogue in English. The members of the cast and crew came from sixteen countries, and English was the only common language among them. In addition, Herzog felt that shooting "Aguirre" in English would improve the film's chances for international distribution. However, the small amount of money that had been set aside for post-synchronization "left Peru with the man in charge of the process; both absconded "en route"." The English-language track was ultimately replaced by a higher-quality German language version, which was post-synched after production was completed. Herzog claims that Kinski requested too much money for the dubbing session, and so his lines were performed by another actor.
