 Originally, a quirky short romantic comedy called The Aquarists was  scheduled to be shot. At 5 am that morning, as the wind picked up  and Heath McKnight was reminded of the 2004 hurricanes, he decided  to write and direct a prequel to the upcoming 9:04 AM (it takes  place 6 months before the movie). While Jon Fordham did camera tests  with the new FX1 and the girls rehearsed the other movie, Heath  wrote the new script (originally called Tres Hermanas) and they shot  it in Heaths master bedroom.
