Reportedly costing more than $200 million, the film was shot in the hills of Kauai, the fourth-largest island in Hawaii, where the crew gathered a team of over 100 members to build the movie's Porto Velho, a bustling river town in the upper Amazon River basin.
To add a sense of reality, the film's creators researched the flora and fauna along the river and sought inspiration from Tupi, an extinct language that was once spoken by tribes in Brazil, to create a dialect specially for the movie.
With its hashtags drawing more than 46 million views on Chinese social media platform Sina Weibo, the film has made 21.1 million yuan ($3.3 million) at the Chinese box office, and was sitting in second place for new releases at the weekend after the biographical film Anita.
