In real life, Adam Plotch' is almost legally blind. Director Miguel Coyula' forbade him from wearing glasses though, as he felt it did not fit his character. Plotch rarely wears contacts due to an eye injury sustained as a teenager. Thus, in all but the phone booth scene, Adam the actor acts and interacts with his fellow actors almost without being able to see them or anything else at all.
When shooting a scene involving a green plastic gun (sprayed with black paint) on an upstate New York highway, two police cars arrived. They had received calls from drivers passing by saying. "There is a maniac in a orange suit pointing with a gun at a girl." The fact that it was a one man crew with such a small digital camera, generated the wrong idea. The policemen stormed out of the cars and handcuffed everybody. Later one of the officers realized that it was a movie when he discovered the small MiniDV camera. The scene was never used in the final cut.
Shot mostly on Sundays over the course of a year.
The producers strongly considered casting multiple actresses in the role of Lily, alternating different performers for each scene's rendition. This had less to do with any artistic choice, and more to do with the fact that they had such a difficult time deciding between a plethora of different, highly talented actresses who showed up to audition, each of whom had different strengths, and performed completely different scenes with varying degrees of skill. Ultimately, Talia Rubel was cast both for her exceptional acting ability as well as the fact that she looked virtually identical to a computerized sketch of what the director imagined the character of Lily to look like.
The original script was about ten pages longer than the one used in the final version of the film. Those additional scenes were actually all shot (although almost none were edited). The excised scenes were not interspersed throughout the film; rather, they all appeared after the action that closes the final scene in the final iteration of the film. The director edited the film sequentially and decided an open ending will be more suggestive for the surreal atmosphere he intended than the more conventional resolution he had scripted.
