Once again, Disneyland plays host to Winston Hibler, the familiar narrator (and sometimes writer/director) of Disney's "True-Life Adventures" short subject series. Hibler describes the various techniques used for making such up-close-and-personal nature documentaries as the then-upcoming Disney theatrical feature Secrets of Life, including the development of miniature lense and stroboscopic "cold" light. Highlights include a foray into a beehive and a visit to an ant colony, and a time-lapse-photography sequence of blossoming plant life to the tune of Maurice Ravel's "Bolero". Searching for Nature's Mysteries originally aired 2 months before the official November 20, 1956 release of Secrets of Life.
