Planning: Genre for my film

I have decided that the genre of my short film will be the thriller genre. I have made this decision because the thriller genre can encompass aspects of many other genres, such as romance or horror. This will allow me more options with the way I shoot the film and the script also. Thrillers also regularly employ the use of devices such as cliffhangers and suspense, which as I am only shooting the opening of the film, gives me a lot of possibilites to make the clip interesting for the viewer.
