Princess Mononoke (もののけ姫, Mononokehime) is a 1997 Japanese epic anime film written and directed by Hayao Miyazaki and produced by Studio Ghibli.
Roger Ebert placed the movie sixth on his top ten movies of 1999. Mononoke also became the highest grossing movie in Japan until Titanic took over the spot several months later. Overall, Mononoke is the third most popular anime movie in Japan, next to 2001's Spirited Away and 2004's Howl's Moving Castle, both by Miyazaki.
It is a jidaigeki (period drama) set in late Muromachi period of Japan, and centers on the struggle between the supernatural guardians of a forest and the humans who consume its resources, as seen by the outsider Ashitaka. "Mononoke" (物の怪, Mononoke) is not a name, but a general term in Japanese for a spirit or monster.
