"House of Nerds," a video shown at the White House Correspondents' Dinner that spoofs the dinner and the politics that surround it, was a year in the making.

Kevin Spacey said the idea originated after last year's dinner, even before "House of Cards" became a Netflix phenomenon.

"By the time we started airing this first season, there was a kind of glee that we got a response to this idea," he told Yeas & Nays. "It was then a process of convincing all the people that we wanted to have do it. Which is never easy; everybody's got to be totally up for it, get the joke, be willing to do things that they might not normally do. And then we all had to be very, very secretive about it."

Spacey filmed about 10 hours for the video in one day, and only appears in scenes with White House Correspondents' Association President Ed Henry. The rest of the cameos were filmed in New York City and D.C.

Spacey participated in a Q&A with MSNBC's Chris Matthews on Tuesday night hosted by the Motion Picture Association of America and Capitol File (the magazine featured Spacey on the cover of its May "power issue"). The MPAA would have had to rate their discussion R, due to all the f-bombs Spacey dropped while discussing his iconic career, up to and including his role as House Majority Whip Frank Underwood on "House of Cards."

Unfortunately, the only hint Spacey dropped regarding Season 2 -- currently filming in the Baltimore area -- was that the Underwood marriage gets even more "interesting."

Real-life House Minority Whip Steny Hoyer, D-Md. -- whose performance in the spoof video Spacey complimented -- dropped by for the event, as did House Minority Leader Nancy Pelosi, D-Calif.

Spacey also nodded to his own politics, telling the crowd: "If Hillary [Clinton] does run, that also means that Bill will be back in the White House, which I think is a good thing."
