‘Alien Worlds’ – All Creatures Great and Small For a show centered on aliens, a surprising amount of the runtime is spent on our green and blue ball of a home. The show will sweep you around the planet from the Danakil Depression in Ethiopia, to the impact crater in the Yucatán Peninsula, to the Cueva de Villa Luz in Mexico. Each of these locations (which appear almost more alien than the carefully painted digital landscapes) serve as jumping points for the planets Atlas, Janus, and Eden. Earthly creatures such as mayflies, ants, and hummingbirds form the basis for the series’ fantastical six-winged sky-grazers, blob-like predators, and the particularly charming ten-eyed pentapods.
