Main Film Genre

I narrowed the choice for the genre of my film down to horror and thriller. I have decided to use the thriller genre, as this can include many aspects of horror and a range of other genres. This will allow for many variations in the script as I have no set guidelines, although I will keep faithful to the thriller genre. Because I am only shooting the opening of a film, I can make sure a lot of suspense is conveyed throughout the opening, and thriller is the perfect genre to do this.
