Claire Underwood (Robin Wright) has assumed her place as the new head of the White House, but nothing ever really goes according to plan on "House of Cards." And a batch of photos from the Netflix show's upcoming sixth and final season introduce some new characters who are surely about to put up some major roadblocks for the new POTUS.

The images feature a first look at new characters played by Diane Lane and Greg Kinnear, who star as Annette and Bill Shepard, a pair of siblings who've just inherited their influential family's massively wealth industrial conglomerate, Shepard Unlimited. According to Netlfix, the sister and brother are "powerful behind-the-scenes force in the American political landscape [who] share a vision for the future of America, as well as a complicated past with the Underwoods."

Considering who the Underwoods are, that "complicated past" language may be a bit redundant. Still, their addition -- along with Cody Fern ("American Crime Story," "American Horror Story"), who's playing Annette's "ambitious and devoted son, who represents the next generation of DC power players" -- should inject some juicy drama into the streaming series.

"House of Cards" has already weathered its fair share of behind-the-scenes drama during production of season six, which saw star Kevin Spacey fired from the show late last year. The actor was accused of sexual misconduct by fellow actor Anthony Rapp when Rapp was only 14, and many members of the "House of Cards" crew soon came forward with tales of their own harassment and abuse at the hands of Spacey. It was later announced that Wright would assume the mantle of the show's leading character, and the series would wrap with a shortened sixth season.

That final outing debuts on Netflix on November 2.
