Patricia Clarkson, Campbell Scott join 'House of Cards'

Feb. 10 (UPI) -- Patricia Clarkson and Campbell Scott are officially headed for House of Cards.

Netflix confirmed at a press event Wednesday in New York that the 57-year-old actress and 55-year-old actor will guest star in Season 5, according to Entertainment Weekly.

The Hollywood Reporter had linked Clarkson and Scott to the political drama in October. Sources said the pair both booked "major roles" and "will be featured heavily" in the new season.

House of Cards is based on the Michael Dobbs novel of the same name, which was previously adapted as a BBC miniseries. The show stars Kevin Spacey, Robin Wright and Michael Kelly.

Senior writers Melissa James Gibson and Frank Pugliese will serve as showrunners for the first time in Season 5. Netflix announced the news in February 2016 following series creator Beau Willimon's departure.

"I welcome Frank and Melissa in their new roles on House of Cards and look forward to collaborating with them and our creative team on Season 5," Spacey said at the time.

The new season of House of Cards will premiere Mar. 30. The show follows politician Frank Underwood (Spacey) as he ruthlessly advances his career in Washington, D.C.

Clarkson is known for playing Sarah O'Connor on Six Feet Under, and has since appeared on Parks and Recreation and Broad City. Scott portrayed Boris Kuester von Jurgens-Ratenicz on Royal Pains, which aired its final episode in July.
