The film was shot over a 16 day period in an actual house located in Berkley, California.
For the duration of the shoot, the cast and crew also resided at the location, literally sleeping on the sets for the shoot.
On the first day of filming, the power in Berkley actually went out due to a rolling black out.
The entire cast and crew consisted of only five people.
There was no sound person present on location. Sound was gathered with a shotgun mic attached to a mic stand. Consequently the sound recorded on location was nearly useless and everything was re-recorded in post production.
