This is such a scrappy little film. The directors partially crowd-funded the project because if you wait for funding to come through, it’s already nearly time to start filming. They wanted to start work on the creatures as soon as possible, and were able to raise enough to do so via an Indiegogo campaign. All effects were practical, and the film was made on a shoestring budget. Yet somehow the final product feels surprisingly polished.
In the end it was worth it. The creatures are truly the stuff of nightmares. One in particular who walks upside-down on its hands and feet in staccato movements (a gimmick we’ve seen a million times in possession films, but… you’ll see in the clip). Well, the one repeatedly ramming the spike through it’s barely-there skull is also pretty inspired.
