The Man from O.R.G.Y. (1970)

A rich man suddenly dies and leaves his vast fortune to a Madam who played a number of female stars for him: Hermione Gingold, Phyllis Diller, Marlene Dietrich, and Bette Davis. She dies too, and leaves her inheritance to her top three 'girls', all living in different parts of the world - and the 'map' to the fortune location can be 'uncovered' only when their three bottoms are placed together. Steve Victor, the agent from ORGY, is assigned to recover them from a kidnapper.
