King Kong vs. Godzilla (Japanese: キングコング対ゴジラ, Hepburn: Kingu Kongu tai Gojira)

 1962 Japanese kaiju film directed by Ishirō Honda, with special effects by Eiji Tsuburaya. Produced and distributed by Toho Co., Ltd, it is the third film in both the Godzilla and King Kong franchises, as well as the first Toho-produced film featuring King Kong. It is also the first time that each character appeared on film in color and widescreen.[5] The film stars Tadao Takashima, Kenji Sahara, Yū Fujiki, Ichirō Arishima, and Mie Hama, with Shoichi Hirose as King Kong and Haruo Nakajima as Godzilla. In the film, Godzilla is reawakened by an American submarine and a pharmaceutical company captures King Kong for promotional uses, which culminate in a battle with Godzilla on Mount Fuji.

The project began with a story outline devised by King Kong stop motion animator Willis O'Brien around 1960, in which Kong battles a giant Frankenstein Monster; O'Brien gave the outline to producer John Beck for development. Behind O'Brien's back and without his knowledge, Beck gave the project to Toho to produce the film, replacing the giant Frankenstein Monster with Godzilla and scrapping O'Brien's original story. King Kong vs. Godzilla was released theatrically in Japan on August 11, 1962 and grossed ¥352 million, making it the second-highest-grossing Japanese film in history upon its release. The film remains the most attended Godzilla film in Japan to date, and is credited with encouraging Toho to prioritize the continuation of the Godzilla series after seven years of dormancy. A heavily re-edited "Americanized" version of the film was released theatrically in the United States and United Kingdom by Universal International Inc. on June 26, 1963.
