Sigourney Weaver Political AnimalsIn her primetime TV series debut, Sigourney Weaver is set to star in Political Animals, USA Network’s 6-episode drama series from Greg Berlanti and Laurence Mark, which premieres this summer. Written by Berlanti, the Washington DC-based series is a fictional look at a former first family that exposes a dynasty weakened by political ambition, lust and greed. It centers on Elaine Barrish (Weaver), the divorced former First Lady and newly appointed Secretary of State who throws herself into the job after recovering from the dissolution of her marriage and losing the presidential nomination. Barrish relies heavily on her son Doug (James Wolk), an ambitious politico who serves as her chief of staff, but is tormented by his twin brother’s struggles with addiction.  With a philandering ex-husband who is still as much in love with her as the office he once held, she attempts to keep her family together, while simultaneously dealing with crises of the State Department and a hungry DC journalist bent on destroying her career. In addition to Wolk, Weaver joins previously cast Brittany Ishibashi as Doug’s fiancée. While launching with a short six-episode order, the Warner Horizon-produced Political Animals is envisioned as a regular series that USA brass hope will run for a number of years. Political Animals reunites Weaver and Berlanti. Avatar star’s only previous TV series appearance was in an episode of Berlanti’s ABC drama Eli Stone, which he co-created with Marc Guggenheim.
