Beyond PRI, Sarah was featured extensively in the TMBG documentary Gigantic, and was one of the four participants (along with John Flansburgh, John Linnell, and AJ Schnack) in the movie's DVD commentary track. She also wrote most of the liner notes for Dial-A-Song: 20 Years Of They Might Be Giants, and wrote The Partly Cloudy Patriot for which TMBG contributed a vast amount of music. Additionally, she has contributed her voice for the shy teenage superhero Violet in the Pixar film, The Incredibles, and wrote and released a non-fiction work, Assassination Vacation. Her bibliography includes works on topics as varied as presidential assassinations, Bostonian Puritans, and manifest destiny.
