Alexa Davalos has signed on for the lead role in Amazon's new pilot The Man in the High Castle, just a few weeks after Luke Kleintank secured the male lead.

The plot is based on Philip K. Dick's 1962 novel of the same name, which is set in an alternate reality where the Nazis and the Japanese Axis powers actually won World War II. In the aftermath of the war, the Nazis took control of the U.S. East Coast, with Japan controlling the West Coast, along a large section in the middle of the country which remained neutral.

Alexa Davalos is playing Juliana, a woman fascinated by Japanese culture who lives in San Francisco under Japan's rule. Juliana's world is turned upside down when a Japanese soldier kills her half sister Trudy, who entrusts her with a propaganda film that is to be delivered to the Restistance's secret headquarters in Colorado. Juliana leaves her comfortable world behind to complete her half sister's mission.

The project was initially conceived as a four-hour mini-series for the BBC, but it never got off the ground. Frank Spotnitz wrote the pilot script and is executive producing alongside Ridley Scott. It isn't known when production will begin on the pilot episode.

Alexa Davalos most recently starred on TNT's short-lived series Mob City. Her feature credits include Stephen King's The Mist, Defiance and Clash of the Titans.
