How did you attract/address your audience?

We based our Thriller on the exisiting film Hard Candy, and so audiences may or may not be aware of the similiarities. The effect use of music and shots effectively appeals to a range of demographics.
The protagonist Ruby appears in the opening scene as a typical, young, teenage girl. There doesn't appear to be anything unusual about her. In some shots we used the popular messenger Window Live, this will relate to modern audiences, particularly those of the younger generation.
The settings in the opening scene are to a certain extenet recognizable. The train station of course is very typical and mondane, whereas Larry's den is very unusual. It's outside, it's dark and dusty, it has no real layout and is filled with abstract props, including the table of pictures.
We used the conventions of eery music to help create suspence throughout the opening. We also used the conventional "male predator", older and darker, and a universally recognized threat to young girls.
The close ups of Ruby place her in an intimate light and therefore help her relate to other young girls watching the film. The use of voyeuristic camera shots also places her in a position of vulnerability and encourages audiences to watch the rest of the film to find out if their heroin survives. The 'train station scene' is likely to intrigue audiences as it's very ambiguous as to who is filming Ruby.
It's not only the camera that is voyeuristic, the audience is to. Throughout the opening the audience sees the parallel of Ruby going to meet Larry, and Larry going to meet Ruby, but in two very different ways. The audience is almost placed in a position of responsibility, they want to warn Ruby that Larry may not be who she thinks he is.
