All of the background people's reactions in the film are real (since none of them are actual extras.) Many of them were confused at what the crew was doing, most notably the man looking at Joey's hammer and sickle illustrations in the sand.
Joey and Boyce are cousins in real life, and their first time working together was on a short film titled 'Knockout' (also produced by Connor McFarlane.)
Stretch Neil Armstrong makes his first appearance in Alien Hunters (Beginnings) filmed in Arizona, where he was purchased.
The film had no production artist but surprisingly came out with a unified color scheme with relaxing and muted browns, teals, greys, and baby blue colors due to the set, locations, and wardrobe.
Many of the ocean scenes were filmed with a camera being held in the actual ocean and had a few close calls.
