Gamera 3: Revenge of Iris

is a 1999 Japanese kaiju film directed by Shusuke Kaneko, written by Kaneko and Kazunori Itō, and produced by Miyuki Nanri, Naoki Sato, and Tsutomu Tsuchikawa. Produced by Daiei Film and distributed by Toho, the film is the 11th entry in the Gamera film series, as well as the third film in the franchise's Heisei period, serving as a sequel to the 1996 film Gamera 2: Attack of Legion.


Three years have passed since Gamera defeated Legion and the world is once again plagued by Gyaos, which have now evolved into Hyper Gyaos. Mayumi Nagamine, noted ornithologist, returns to aid the Japanese government in addressing this threat. A graveyard of Gamera fossils is found at the bottom of the sea. Shadowy government agents, occultist Miss Asakura and Kurata Shinya, are meanwhile working with a different agenda, with Asakura believing Gamera to be an evil spirit.
