In the film, the words of John and Abigail Adams and Thomas Jefferson are drawn from their letters, diaries, and other writings.

The description of John Adams railing against the grand estates of the Virginians and his proposal that his own "comfortable but humble" farm be called "Montezillo" comes from Joseph Ellis's Passionate Sage, page 58.
