Tong Tana: A Journey to the Heart of Borneo is a 1989 Swedish documentary film about the Penan people of Sarawak, Borneo, a federal state of Malaysia, and their struggle to protect their tropical rainforest.[1] Central to the film is the story of Swiss environmental activist, Bruno Manser, who was targeted by the Malaysian government for protesting the lumber industry's logging operations.[1] Ten years later, the TV crew returned to the area and filmed Tong Tana: The Lost Paradise, which documented their struggle to protect what was left after their homeland was logged.[2]
Filmmakers Jan Roed, Fredrik von Krusenstjerna, Bjorn Cederberg and Kristian Petri worked on the first documentary.[1] A 1991 review in the Los Angeles Times called the first film "as beautiful as it is heartbreaking".[1]
In May 2000, shortly after the second film was completed, Manser disappeared without a trace and was presumed dead.[2]
