Actor Kevin Spacey on Sunday insisted that the dramatic return of “House of Cards” -- being binge-watched by much of Washington -- is rooted in the realities of how the nation's capital operates.

"We can get done shooting on a day and I'll come home and turn on the news and think: 'You know, our storylines are not that crazy, they're really not,' ” Spacey told ABC's “This Week.”

Without getting into spoilers, the second season of the Netflix drama begins with a murderous subplot that shocked many viewers of the show.

And Spacey, who plays the House majority whip turned vice president, says perhaps the least realistic segment of the program is that Republicans and Democrats can actually work together.

“Some people feel that 99 percent of the show is accurate and that the 1 percent that isn't is that you could never get an education bill passed like that," Spacey told ABC.

And having shadowed House Majority Whip Kevin McCarthy, R-Calif., Spacey noted that his real-life counterpart was somewhat jealous of how his character operates.

"He actually said recently that, 'If I could kill just one member of Congress, I'd never have to worry about another vote,' " Spacey said of the California Republican.
