'Political Animals'' Sigourney Weaver: 'Never Call a Bitch a Bitch' (Exclusive Video)

Sigourney Weaver's Political Animals alter ego Elaine Barrish has some wise words for Carla Gugino's enterprising reporter Susan Berg.

"Never call a bitch a bitch, us bitches hate that."

In an exclusive clip from USA Network's upcoming Greg Berlanti and Laurence  Mark miniseries, the actress offers an inside look at her fierce character, the Secretary of State with an eye on the White House's top job.

In the series, which premieres July 15, Weaver's character must juggle the demands of Washington, D.C., with her complicated family that includes two sons -- one who helps with her political career (James Wolk) and another (Sebastian Stan) who has a whole set of issues with the clan.

In addition to living with her mother (Ellen Burstyn), a former Las Vegas showgirl, Barrish also has to contend with her ex-husband, who just happens to be the flamboyant former president Bud Hammond (Ciaran Hinds) whom she may or may not still be interested in her depending on how many drinks they've had.

"A 'political animal' is someone who can not stay away from this world because there is such a potential to do good and to make a difference," Weaver explains in the clip, exclusive to The Hollywood Reporter. "You have to be willing to deal with a lot of the corruption, you have to be so committed to the public good that you're willing to navigate that."

"[The series] grapples with what the true concerns are leading this country and what the true challenges are of trying to lead a good life in politics," she says. "This contrast between the public and the private life, you sense the cost people pay to be in politics."

Political Animals premieres Sunday, July 15 at 10 p.m. on USA Network. Check out the clip, above, and hit the comments with your thoughts on the series. Will you watch?
