The big cats of Africa have always been favored subjects of wildlife filmmakers. But as little as 15 years ago, no one had captured the unforgettable image of a leopard in its ghostly nocturnal stalk. Viewers had never seen intimate portrayals of the sleek and elusive serval, or witnessed the nighttime romps of the beautiful black-eared caracal.

The team of Owen Newman and Amanda Barrett filled those gaps with a series of spectacular breakthrough films in the 1990s. Among the first to apply infrared light and night vision goggles to wildlife studies, they combined technology with intrepid determination and a strong dose of luck, illuminating the cats we hardly knew, and giving us fresh insights into those we only thought we knew, such as lions and cheetahs.
