The zombies are often seen drooling, this is in fact chocolate sauce.
The original cinematographer was replaced after only one day. Due to a lack of time (and no replacement) the film was shot entirely by the director who had to learn much of the camera equipment and lighting as the production went along. The director has expressed disappointment with much of the overall look of the film.
The film took 17 days to shoot on a production budget of $6000.
Originally planned as a short film in early 2009. It was then expanded into a feature film shortly after with only one month of pre-production. Was meant as a fun "pet project" while the filmmakers were waiting for a bigger project to get off the ground.
Many of the zombies seen during the forest scenes are played by the same actors, but in different costume and make up (mostly the films production team).
