Woody Allen takes the Japanese action film Kokusai himitsu keisatsu: Kagi no kagi (1965) and re-dubs it, changing the plot to make it revolve around a secret egg salad recipe.
From memory: A silly parody at the expense of a Japanese movie, entertaining for what it is.
Halliwell*: "Woody Allen and his American cast re-dub a Japanese spy film to create an off-beat comedy that is amusing in fits and starts."
Maltin***: "...one long, very funny joke"
