Phil and Lynne Richardson spent four years camping at a watering hole in northern Zimbabwe with the lions that live there. From National Geographic:
Walking With Lions is more than just another wildlife documentary… What’s unique about these films, particularly with lions, is that the filming is done out of the vehicles. It’s done by foot, and lions are very dangerous animals. The Richardsons decided to film the wildlife on foot because this particular spring was surrounded by a gorge and impossible to reach by vehicle. This spring was the only source of water for miles around, and one pride of lions had made this their home, an ambush site for wildlife that come to the spring to drink.
The result is an amazing documentary that follows the lives of a generation of lions and shows their their encounters with the water buffalo, elephants, and other animals that rely on the spring in intimate detail.
