The stars of "House of Cards" took to Twitter on Thursday to answer questions from fans.

Kevin Spacey, who plays viciously ruthless politician Frank Underwood, signed on for the Q&A, as did Robin Wright (Claire Underwood), Michael Kelly (Doug Stamper), Michael Gil (President Walker) and series creator Beau Willimon.

Fans turned out in force for the chat -- so many that the hashtag #AskHOC became one of the top Twitter trends on Wednesday afternoon.

Some of those participants are famous in their own right. "Breaking Bad" star Aaron Paul chimed in with two very important questions. (Stars, they're just like us, right?)

And Kate Mara, who plays journalist Zoe Barnes, also poised a (somewhat spoilery, if you haven't started the new season yet) question of her own, which was answered by Willimon:

The second season of "House of Cards" was released on Netflix last month, and Willimon told CBS News he's already working on the script for season 3.

Tell us: What did you think of season 2 of "House of Cards"?
