I’ve learned that USA Network has decided to push its alien drama pilot Horizon to summer. The project, from The Walking Dead executive producer Gale Anne Hurd, received a cast contingent pilot order in early December. After the network made some efforts casting the lead, I hear the USA brass decided to wait until the end of the broadcast pilot season when more talent will be available. Right now, Horizon was competing with some 50 broadcast drama pilots for top actresses. Horizon is USA’s first genre effort in eight years and the first-ever period drama on the network, so I hear USA executives wanted to give it the best chance possible. Set during the height of World War II, Horizon centers on a secretary at the FBI who discovers that her husband might have been killed in a battle with a spaceship in the South Pacific. Obsessed with learning the truth, she becomes the only person standing between Earth and an alien invasion. Bridget Tyler (Burn Notice) wrote the script and will co-executive produce for Universal Cable Prods and Hurd’s Valhalla Entertainment.
