Steve has partnered with the film's producer, Bernie Goldmann on a few projects.
Bernie, who was a producer on "300", initially questioned whether animation was a viable technique for a horror film.
Casting aside the obvious shortcomings of the trailer (the second year Maya student camera work, why are two people sitting in a giant empty space when monsters are hunting them?, how much good will that crowbar do if she's not changing tires?) the question of "appropriate technique" is a good one.
There have been a few feature length animated films to touch on horror. Most notably Satoshi Kon's "Perfect Blue" and the Japanese classic "Vampire Hunter D". The French anthology "Fear of Dark" comes close too. These offer more cerebral scares than the classics of the genre not even approaching the primal fear conjured by "Night of the Living Dead" or "Halloween". Even the psychological terror of films like "Rosemary's Baby" and "Repulsion" is leagues beyond any attempts with animation.
The horror film's power comes from psychology. It comes from the viewer's identification with the actor/character and the subsequent stirring of pity and fear in the viewer.
Animation inherently alienates the viewer from the film -the barriers against that same identification are too high.
