Suspense are an important feature in Thriller films. Supspense is there to build up tension by either foreshadowing future events, leaving unanswered questions that will leave the audience desperarate to know.Suspense is also used to create a drama which would create an visceral effect. For example a scream in terror , heartr rate increase (effects on our physical bodies). in most thrillers the audience watching know more than the characters in the scene.For example 'The Bomb theory' by Alfred Hitchcock. Also the movie 'The rope' is where a dead body is put in a drawer but the characters in the scence do not know whereas the audience do ,this causes suspense because the audience are waiting for when the characters find out. Suspense is done to leave the audience at the edge of their seat.
Suspense can also be created through the false plateau ,this lulls the audience into a false sense of security.For example in 'Jaws' little children were playing a pratical joke by pretending they are 'Jaws' using a fake shark fin made out of cardboard.The audience then relaxes ,then the real jaws attacks! That made the attack more horrifying.
