Next Saturday, BBC America presents the latest nature documentary series from the Planet Earth team, presented by Sir David Attenborough: Dynasties, which will be simulcast on three other sister networks from the dynasty owning BBC America and other cable outlets. It’s certainly worth waiting for, but in the meantime, BBC America sets the table, all this week, by holding a mega-marathon of reruns of the various editions of the magnificent Planet Earth franchise. The food-chain action starts today at 6 a.m. ET, and doesn’t stop for an entire week, until the premiere of Dynasties caps the festivities. So remember: all this week, all day and all night, whenever insomnia keeps you up or politics brings you down, you can turn to BBC America and see something spectacular. And beautiful.
