It started as a small project, but when people and friends heard about it (because it was directed and produced by David and Teresa), it became bigger and bigger. They had to write more characters and cameos, and more locations were added; so a weekend movie became a "real deal" production.
The film was shot in 5 days, although it was planned to do it in 3 (a free weekend that David had), but due to the increasing number of people involved in the project and the number of locations added, two more days were needed in order to complete the shooting.
The film was set and originally written to take place in only 3 locations, but because of the final number of people involved it ended up being shot in 12.
