The first two seasons together cost $100 million to produce.
In season 3, Doug Stamper's (Michael Kelly) niece and nephew are played by his real-life children, Frankie and Clinton.
Production was based in a 300,000+ sq. ft. warehouse in the fashion industrial district in Joppa, Maryland. The set is actually part of an older Macy's distribution center, and all the driving scenes were performed in a green screen room, which served as a refrigerator for fur coats. Inside the building the following sets can be found: Oval Office, the Underwood home (upper lower and main levels), House of Representatives, various state representative's offices, South Carolina governor's office, various plush hotel suites.
Director David Fincher stated that every main cast member was their first choice. In the first read through, he said "I want everybody here to know that you represent our first choice - each actor here represents our first choice for these characters. So do not fuck this up."
