Animal Planet has scheduled the first three of six monthly Mutual of Omaha's Wild Kingdom specials. The first primetime hour is set for Sept. 17, Lost Elephants of Timbuktu. That will be followed Oct. 8 by Great Cats of India and Nov. 12 by Black Mamba. Three other hour-long programs in the Wild Kingdom package are due next year, with airdates not yet decided. Two of those programs will focus on amphibians and snakebites. The program will be promoted by the insurer on select United Air Lines Inc. domestic flights and at the Animal Planet booth at various dog shows, as well as via on-air promos across the Discovery Networks U.S. family and in Discovery Channel retail stores. Mutual of Omaha's Wild Kingdom ran as a weekly half-hour series from the 1960s through the mid-1980s, first in Sunday primetime on NBC, then in barter syndication.
