who our target audience is

It really depends on the kind of thriller film. Like all genres, there are sub-genres and to really give an accurate answer to your question you would have to specify what kind of thriller film. Silence of the Lambs and No Country for Old Men are considered the two best thrillers in recent memory, and they're rated R. Their target audience was probably for the young male adults. Meanwhile, there are those thrillers that are borderline horror films, such as M. Night Shyamalan films The Sixth Sense, Signs, The Village. Since they're close to horror (and horror films target teenagers, but I feel as if the majority of this group is lightly to be teenage girl), the demographic would be slightly different, probably younger and more female based. And then there are legal thrillers (Fracture, Runaway Jury) and crime thrillers (Memento, Se7en) that target a more mature audience, and classic thrillers (any Alfred Hitchcock film) that are rated PG, but are intended for adults. But if you just need a target audience for a generic thriller film.

I'd have to say the young adult demographic from 18-25, would like my thriller simply because I feel as this type of sub-genre has not been approached enough, the one other film that I can relate to it is cabin fever, about a group of college graduates who rent a cabin in the woods and begin to fall victim to a flesh-eating virus. This is similar to mine in the way that the there is an element of a meat infecting virus being transfused between people, the only difference is that mine is more world wide and not just targeting a small group of teenagers trying to escape high school for the summer. But now I begin to take this idea away from the hills of America were the problem can be isolated but now putting it into your kitchen then onto your laps.
