The BBC Earth-PBS miniseries Spy in the Wild wouldn’t be possible without its animatronic creatures. Thanks to their realistic movements and designs, the robot spies have allowed filmmakers to capture up-close-and-personal footage of animals in their natural habitats. This clip spotted by Sploid takes a closer look at how these covert operators function. Follow special effects artist John Nolan inside his London studio to see what models of an African wild dog pup and a meerkat look like without their skin.
