In season one, episode two, "New Colossus", when Prairie and her parents are taking a family photo, we hear the photographer say, "...Prairie, toward the sound of my voice, honey..." to get her attention. The Sound of My Voice (2011) is the first feature-length film by both Zal Batmanlij and Brit Marling.
Many names of crew who worked on the previous episode - some of whom also worked on this one - are hidden in the background of the cafeteria set. The windows at the back of the room are painted as if listing the school's team champions from some unspecified sport. On the Champs 2014 windows are Chris Seehase, Mitchell Andrew Lillian (as "Mitch Lillian"), Cameron Sizemore, Glen A. Gregory, Tom Anderson, Matthew Selkirk, Brent Knobloch, Jon Goracy and Brad Kenny. The Champs 2015 windows include Alexandra Olender (as Allie Olender), Lauren O'Brien (as Lauren Holz), Karine Benzaria, Hinju Kim, Leah Reingewirtz and Stephanie Abbaspour. Finally, on the Champs 2016 windows you can just make out George Doherty.
