Although the plot of the movie takes place in the Amazon, the shooting of the film took place in Hawaii, many scenes of the port city and the railway were filmed there. And most of the jungle scenes were already filmed in the Atlanta studios. The film crew spent a lot of time exploring the flora and fauna of the Amazonian jungle, including several expeditions. They did this to create a realistic and lively picture.

Scene was shot in real scenery. This whole huge building was erected on the banks of the reservoir specifically for filming. Yes, it's hard to believe, but these are not real colonial buildings from 1910, but simply a scenery, and not the only one built for this film. An interesting fact is that indoor shooting was also done in this city, i.e. these are not just plain walls, but worked out interior. According to the director, such decision was made for more natural lighting and creating the right atmosphere.
