Kokusai himitsu keisatsu: Kagi no kagi (国際秘密警察 鍵の鍵, International Secret Police: Key of Keys), also known as Key of Keys, is a 1965 Japanese comedy-spy movie directed by Senkichi Taniguchi. It is the fourth installment of five movies in the Kokusai himitsu keisatsu series, a parody of James Bond-style spy movies.

Woody Allen used this movie, combined with footage from the third installment Kokusai himitsu keisatsu: Kayaku no taru (国際秘密警察:火薬の樽, International Secret Police: Keg of Gunpowder), to create his directorial debut, '', in which the original dialogue is redubbed in English to make the plot about a secret egg salad recipe.

As part of Toho's "International Secret Police Series" 3rd part "Keg of Gunpowder" and 4th part "Key of Keys" were replaced by American movie director and actor Woody Allen, and a scene was added to take a picture of the bone. It was re-edited into one comedy gag movie.

The Japanese actors have also appeared in the movie but different names such as Tatsuya Mihashi ("Phil Moscowitz"), Akiko Wakabayashi ("Suki Yaki"), Mie Hama ("Teri Yaki"), Tadao Nakamaru ("Shepherd Wong"), and Susumu Kurobe ("Wing Fat"). With stereotyped Asian customs as a laughing point, it is a careful parody of spy movies represented by the "007 series" at that time.

The content is also a mess that an international spy played by Phil regains the "world's best egg salad recipe" stolen in a certain country, but although it is a parody, it is also Woody Allen's first directorial movie. It is a work and is still highly evaluated by American movie critics.

However, Woody himself is said to be extremely avoiding touching this movie. He would appeared in Casino Royale in 1967 back in England as Jimmy Bond. DVDs are also on sale overseas, but in Japan, they haven't seen the movie due to issues such as copyrights with Toho, Japan's major movie studio company.

Mie Hama and Akiko Wakabayashi would latter be chosen by Eon Productions for the sixth James Bond movie, You Only Live Twice'' a year later as Bond girls.
