Sigourney Weaver has just joined the growing list of big-screen talent transitioning into small-screen projects.

The "Avatar" actress has signed on for USA Network's series "Political Animals," the network said today. In her series TV debut, Weaver will play Elaine Barrish, a divorced former First Lady and current Secretary of State who throws herself into the job after recovering from the dissolution of her marriage and losing the presidential nomination.

The mini-series, from Greg Berlanti ("Brothers & Sisters" and Laurence Mark ("Dreamgirls"), will be six hours in duration, with a premiere slated for this summer.
