As previously reported, the six-episode drama, created by Greg Berlanti, Laurence Mark and Warner Horizon, is scheduled to premiere this summer.

Also in the cast are Tony nominee Sigourney Weaver (Hurlyburly), Kristine Nielsen (Bloody Bloody Andrew Jackson), James Wolk, Sebastian Stan (Talk Radio), Brittany Ishibashi, Ciarán Hinds (The Seafarer) and Carla Gugino (The Road to Mecca).

The 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 (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 (Hinds) 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 (Gugino) bent on destroying her career."

Burstyn will play Elaine's mother, Margaret Barrish, a tough Chicago broad and one-time Vegas showgirl.

Burstyn won the Tony Award in 1975 for her performance in Same Time, Next Year. She has also been seen on Broadway in Oldest Living Confederate Widow Tells All, Sacrilege and Shimada, among others. For more on Burstyn's theatrical history, visit the Playbill Vault.
