An Emmy-winning and Oscar-nominated actress has been tapped to play the feared first ex-wife of Nick Offerman’s Ron Swanson on "Parks and Recreation," reports TVLine.com.

Patricia Clarkson, known for Emmy-winning turns on “Six Feet Under” and for film roles including “The Green Mile” and “Far From Heaven,” will tackle the role of Tammy 1, according to the report.

The season finale of the NBC comedy showed the character from behind, without revealing her face or other characteristics. The arrival of Tammy 1 sent Swanson’s second ex-wife, Tammy 2, who is played by Megan Mullally, fleeing in fear.

“Tammy 1 is her own specific brand of demon. I think we came up with backstory for her that’s both funny and illuminating and also answers all of the questions that you would have when seeing people’s reactions to her presence in the finale," said executive producer Michael Schur earlier this month, according to TVGuide.com.

Clarkson twice won Emmys as outstanding guest actress on “Six Feet Under,” in 2002 and 2006. She was nominated for an Academy Award as best supporting actress in 2004 for “Pieces of April.”
