A character in the script who was eventually cut, was played by an actor who passed away during the shooting schedule.
Melancholy and the Nonchalants, the band who wrote and performed the score for the film, were found by Carlson in a New York subway station while traveling from Brooklyn to Manhattan.
The film partially takes place in the winter of 2001. However, it was shot in the fall of 2010.
Carlson encouraged improvisation on set. In the Battery Park scene, Carlson secretly asked Rachel Marie Lewis (Mandie) to ask Kevin Pinassi (Alex) "Are you afraid of dying". The reaction of Pinassi in that scene was genuine and the lines that followed were improvisation.
The main character was partially based on a real life man from writer/director Erik Peter Carlson's hometown. Carlson made a documentary of this individual in 1999, which followed a day in the life of a man who was recently released from a mental institution.
