Research and Planning - Film genre's

There are many different types of film genre in which i can base my film trailer about. One of which is horror. The first horror movie ever made was in 1896 by an imaginative film maker called Georges Melies in which he created a 2 minute long movie called 'Le Manoir Du Diable' also known as the Devils house. This film terrified audiences all over France and England and i would hope to recreate the same effect to my potential target audience.
