Suspense is when there is a build up of feelings that cause uncertainty and tension. This is normally caused by certain actions, normally when watching thrillers. Suspense is commonly used in thrillers, as it creates a mental state on curiosity and anxiousness. This causes them to feel strain as they sit on the edge of their seat wondering what will happen. Suspense will normally operate in a situation where there is a lead up towards a big scene or event so it gives a very tension wondering feeling to create a sense emotion and excitement towards the scene.
However Alfred Hitchcock describes the difference between suspense and mystery as they can seem the same thing. Mystery is a clever process where the audience will want to know what happens next a wondering feeling. However suspense is an emotional process.
