The "Oklahoma Sunshine" shown in the film was actually a vial of Brawndo - The Thirst Mutilator.
The entire project was written, shot and edited in less than 48 hours, as part of the 2009 Los Angeles 48 Hour Film Project. All entries to the festival were required to include the following: Junk Mail as a prop, a character named Alex or Alexis Filburt (champion), and the line of dialogue "How was I to know?".
