The camera shown in a prologue scene with Mikki Lomack (Lisa Morrison) is the actual production camera used in the original Savage Harvest (1994). Most of the footage of Mikki Lomack was shot with this camera.
On the night before Thanksgiving in 2002, writer/director Jason Christ was involved in a car accident that resulted in the temporary halting of production. The production resumed in March of 2003.
The farm seen in the second half of the film was affectionately referred to by the cast and crew as "The Death Farm" and is actually a functioning farm that has been owned and operated by writer/director Jason Christ's family since 1960.
In scene 60, the first major fight sequence of the film between the protagonists and the demon-possessed, a majority of the footage was lost due to camera malfunctions, which resulted in a re-shoot of nearly the entire sequence. This would not be the last scene that would be affected by camera problems.
Lisa Morrison was forced to leave the production to serve a tour of duty in Iraq for the US Army before she completed all of her scenes for the film. The remaining scene that she was not able to appear in was a hallucinogenic nightmare sequence (scene 33) with Ashley Lomack (Emily Haack) that had to be completely rewritten to involve the Mikki Lomack character without having Lisa on set.
