 Early this month, USA announced it had snagged flick star Sigourney Weaver to make her debut as a TV series regular in the “event drama” from Greg Berlanti (“Brothers & Sisters,” “Everwood”) and Laurence Mark (“Dreamgirls,” “Jerry Maguire”).

 The short-order series is, USA says, a fictional look at a former First Lady who was married to a philandering POTUS, and who is now the newly appointed Secretary of State, after making a failed run at the White House.

 New Secy of State Elaine Barrish, played by Weaver, and her former President husband, Bud Hammond, have – two sons.

 One is a Lost Soul, who struggles with addiction, named T.J. – that’s Stan. The other, the Good Son, is named Douglas and is his mother’s chief of staff; he’s played by James Wolk (“Lonestar”). Douglas has a fiancée named Anne, played by Brittany Ishibashi (“Parenthood,” “Fairly Legal”).

 Also in the mix is a hungry Washington journalist who is bent on destroying the Secy of State’s career, played by Carla Gugino.

 Only one more bit of major casting to announce: who will play Bill…er, Bud.
