The Netflix series will also be bringing back another character.

Some new faces are coming to House of Cards.

ET can confirm that the Netflix series has cast Diane Lane and Greg Kinnear for the upcoming sixth and final season of the series. The Oscar-nominated actors will portray a brother-sister duo.

House of Cards also confirms that Robin Wright, Michael Kelly, Jayne Atkinson, Patricia Clarkson, Derek Cecil, Campbell Scott and Boris McGiver will be returning to the show -- but a more shocking return is Constance Zimmer's character, Janine Skorsky, who fled Washington D.C. in the first season only to make an appearance in a season 4 episode. 

It is still yet to be confirmed if Neve Campbell's character, LeAnn Harvey, will be back on House of Cards, as her fate was left a mystery at the end of last season.

In December, ET learned that the series was scheduled to resume production early this year on the eight episodes of the final season, but Kevin Spacey, who played leading man Francis Underwood, would not be returning.

The news came after Netflix announced that they no longer wanted to be involved in "any further production of House of Cards" that included the 58-year-old actor, who was accused of sexual assault and misconduct by several men. Through his lawyer, Spacey has denied all of these allegations.

Netflix's chief content officer Ted Sarandos further revealed to Variety that the final season will now star Robin Wright, who portrays Francis Underwood's politically savvy estranged wife, Claire. "We were really excited we could get to an agreement… for the conclusion of the show," he told the trade publication.
