The film was first written about a male/female couple with a man named Sergio, but Miguel Arteta and Alia Shawkat had much difficulty casting the role. Once Laia Costa auditioned for the film, they felt that she had just the right grasp on the character, so they changed the story to two females.
All of the dialogue was improvised.
Filming took 10 days; the film's second act was shot in real time over the course of 24 hours.
Alia Shawkat created and co-wrote this film.
Alia Shawkat and Mae Whitman co-starred in "State of Grace" and "Arrested Development".
