As narrated by Alec Baldwin, the unique National Geographic documentary miniseries GREAT MIGRATIONS undertakes an ambitious and seemingly impossible task: cinematically tracking the geographic relocations that many animals make perennially, to ensure the survival of their respective species. To capture this unusually intimate footage of animals on the move, the program was filmed on ice floes, in cliff binds, underwater, and in many other challenging locations. This set contains the entire miniseries as it originally aired on television.
