Couldn't get enough of Planet Earth's wide-ranging exploration of nature? We have good news. Netflix is producing a spiritual sequel, Our Planet, with the help of both Silverback Films (which made the original BBC show) and the World Wildlife Fund. The eight-episode series will reportedly venture into "never-before-filmed" corners of the globe, with everything shot in 4K -- just like Planet Earth, the new production will serve as a good showcase for your TV. You'll have to be patient, however. Our Planet isn't expected to debut until 2019, so you'll want to find some other nature documentaries to tide you over.
