The movie was shot in one day with eight cameras continuously rolling in different areas of the house. Actors were given the freedom to create their own subplots based off their given character bios.
The movie was almost entirely improvised based on individual character bios. Only Peter Curtis Pardini and Jake Thomas Armbruster knew the overall story map. This way, the actors would only be acting based off their motivation and previous knowledge of their character's past, not on what was specifically going to happen.
The only written dialogue was in the short film within the movie (written by Peter Curtis Pardini and Jake Thomas Armbruster) and the final monologue delivered by Wes Studi, which Pardini wrote the day before the shoot.
