Sebastian Stan (Captain America, Gossip Girl) is set to co-star in Political Animals, USA Network’s 6-episode drama series from Greg Berlanti, Laurence Mark and Warner Horizon, 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 (Sigourney 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. She attempts to keep her family together, while simultaneously dealing with crises of the State Department and a hungry DC journalist (Carla Gugino) bent on destroying her career. Romanian-born Stan, repped by WME and Brookside Artist Management, will play Barrish’s son Thomas “T.J.” Hammond, a lost soul who struggles with addiction and the polar opposite of his brother, Douglas (James Wolk), who serves as their mother’s chief of staff.
