The Walking Director executive producer Gale Anne Hurd is moving from horror to sci-fi with the alien invasion drama Horizons, which was just picked up by USA. There's an additional bit of info, though, that moves this show from "Huh, OK, this could be cool" to "When will this air? Give it to me now!" Namely: It's set during World War II. USA has discovered the key to my heart, and it is the phrase "sci-fi period drama."
