If I take a movie example from my last post it would be Donnie Darko, only because the audience for that is very specific.
Donnie Darko. While making Donnie Darko there was a chance that it may not be as popular as it was, so the film makers had to make sure people knew what it was about before they chose to see it. They did this by how they advertised it, they advertised it specifically as a psychological thriller that would possibly scare you. Their target audience were mature enough to appreciate the film at 15 and above so they advertised it as not suitable for anyone younger than that.
Thriller audiences are always quite similar no matter the sub-genre. Thriller audiences are usually people old enough to understand the plot and people who want to be put in suspense but also want a movie that makes them wonder a little. A horror does the suspense but horror films don't always have the best plot lines.
