Miyazaki did not want to create an accurate history of Medieval Japan, and wanted to "portray the very beginnings of the seemingly insoluble conflict between the natural world and modern industrial civilization." The landscapes appearing in the film were inspired by Yakushima. Despite being set during the Muromachi period, the actual time period of "Princess Mononoke" depicts a "symbolic neverwhen clash of three proto-Japanese races (the Jomon, Yamato and Emishi)." "Princess Mononoke" was produced with an estimated budget of ¥2.35 billion (approximately US$23.5 million). It was mostly hand-drawn, but incorporates some use of computer animation in approximately ten percent of the film. The computer animated parts are designed to blend in and support the traditional cel animation, and are mainly used in images consisting of a mixture of computer generated graphics and traditional drawing. A further 10 minutes uses inked-and-painted, a technique used in all subsequent Studio Ghibli films. Most of the film is colored with traditional paint, based on the color schemes designed by Miyazaki and Michiyo Yasuda. However, producers agreed on the installation of computers to successfully complete the film prior to the Japanese premiere date. Telecom Animation Film Company helped animate the film. DR Movie helped with the painting process. Two titles were originally considered for the film. One, ultimately chosen, has been translated into English as "Princess Mononoke". The other title can be translated into English as either "The Story of Ashitaka" or "The Legend of Ashitaka". In a Tokyo Broadcasting System program, televised on November 26, 2013, Toshio Suzuki mentioned that Hayao Miyazaki had preferred "The Legend of Ashitaka" as the title while Suzuki himself favoured "Princess Mononoke". Suzuki also mentioned that Miyazaki had created a new kanji to write his preferred title. The English dub contains minor additional voice overs to explain nuances of Japanese culture to western audiences. A central theme of "Princess Mononoke" is the environment. The film centers on the adventure of Ashitaka as he journeys to the west to undo a fatal curse inflicted upon him by Nago, a boar turned into a demon by Eboshi. Michelle J. Smith and Elizabeth Parsons said that the film "makes heroes of outsiders in all identity politics categories and blurs the stereotypes that usually define such characters". In the case of the deer god's destruction of the forest and Tataraba, Smith and Parsons said that the "supernatural forces of destruction are unleashed by humans greedily consuming natural resources".
