Genre Research-

To begin with, the difference between a Thriller film and a Horror film is...

In a thriller the aim is to be worried for the character, on the edge of your seat wondering whats going to happen to them.

Then in a Horror the aim is to make you scared by having scary music to create tension and make you tense and making you release that tension by either a climax or an anti-climax.

 The thriller genre uses suspense, tension and excitement as its main elements. They are heavily stimulate the viewer's moods, giving them a high level of anticipation, ultra-heightened expectation, uncertainty, surprise, anxiety and/or terror.
The most common subgenres are psychological thrillers, crime thrillers, erotic thrillers and mystery thrillers.
