In Like Flint (1967)

After observing the launch of a new space platform, Z.O.W.I.E. Chief Lloyd C. Cramden joins President Trent for a game of golf. Their game is interrupted by a small group, two women disguised as boys and an actor disguised as an old man, all from the Fabulous Face organization. Substituting the presidential golf ball with a small gas bomb, they succeed in temporarily immobilizing the presidential party and replacing the president with the now-undisguised actor, who has been surgically altered to look exactly like him. The Fabulous Face organization plans to gain control of the world and run it entirely by a group of women led by Elisabeth; Cramden has inadvertently stumbled upon this world-domination plot. The women want to establish a matriarchy, and the first step in their plan is to gain control of a US space facility in the Virgin Islands. Elisabeth has established the spa there as a cover. The women establish their headquarters near the rocket base to brainwash their male-oriented sisters by planting tape recorders in their hair dryers.

Puzzled by an apparent three-minute time discrepancy – revealed by a perusal of a stopwatch that was active during the switch – Cramden visits the former super agent Derek Flint at his New York City home. Greeted by Flints’ three female live-in companions in the living room of Flint’s spacious Manhattan apartment, Cramden is informed that Flint is experimenting with the creation of a dolphin language dictionary. Flint tells Cramden these undersea mammals are intelligent creatures and that they use sounds or sonics to communicate, a notion that had been only relatively recently reinforced by scientific experimentation at the time the film was produced.
