The 4K wildflife documentary Netflix promised us isn't slated to debut until 2019, but you won't have to wait that long to see vivid images of nature on TV. BBC's gearing up for the release of Planet Earth II, its six-part follow-up to the original Planet Earth series shown in 2006, later this year. Just like the original series, the six, one-hour episodes will explore jungles (both real ones and concrete), deserts, grasslands "and the extraordinary ways animals survive within them." This time, though, BBC captured the planet's habitats on cam entirely in 4K.
