Some time ago, we heard that 'The Walking Dead' executive producer Gale Anne Hurd had begun development on a new period sci-fi TV series for USA titled 'Horizon,' a World War II-set tale of aliens and intrigue. Now that drama has its first major star: fresh off his recent run on the eighth season of 'Psych,' onetime 'Princess Bride' star Cary Elwes has boarded 'Horizon' in a leading role.

According to The Hollywood Reporter, Elwes will take the role of Max Hartman, a mysterious man who leads a double life in Washington, D.C. His supposedly tragic past prompts him to question whether to follow orders or do what he believes to be right.

Set at the peak of World War II, ‘Horizon’ follows an FBI secretary ('Big Thunder' star Ruth Bradley) who finds out that her husband may have been killed in a battle with a spaceship while in the South Pacific, and in her obsessive investigation inadvertently becomes “the only person standing between Earth and an alien invasion. The cast also includes Meg Steedle ('Boardwalk Empire'), Mark Famiglietti and Taylor Handley.

Hurd will executive produce the drama, with the pilot episode written and co-executive produced by Bridget Tyler (‘Burn Notice’).

Well, what say you? Are you intrigued by the thought of USA's 'Horizon,' now that Cary Elwes has joined the cast?
