Conventions of a thriller genre

Alfred Hitchcock is an English film maker/producer who uses these conventions for a thriller. He preferred to use the suspense technique (instead of surprise) in thriller genres. Hitchcock once said "It's not the bang that scares you, but the anticipation of it". The visual sequences he used enable his films to unfold fluently.
"Psycho" uses dark lighting apart from a centre key light that shines on the main character, Marion. Not only does this soft lighting surround her, but the mise en scene behind her contains round picture frames. The other character, Norman, is harshly lit with angular picture frames behind him. The camera also views him from both sides of his face, whereas Marion has a full front preview. False suspense makes the viewer surprised and interested because we never know what will happen. Hitchcock creates false suspense in a number of ways. When Marion has been sleeping in the side of the road in her car, a cop comes and wakes her up. The audience feels tense and wonders if she is going to get caught with the $40,000. Marion is very nervous and we are afraid if the cop is going to search her bag. Her uneasy behaviour adds to the tension. The policeman's sunglasses add to the tension because we cannot see his eyes, hiding his identity.
Commonly, he uses a device whereby the audience knows something that the characters don't know. For example, people are sitting around a table, under which is a bomb ticking away, the people at the table don't know it's there, but the audience does. I will take this into account when creating my main task; the audience will know for definite that the ex-husband/father is stalking his daughter, when he thinks he's stalking his ex-wife. This creates suspense for the audience and eagerness to know what is going to happen next.

Alfred Hitchcock uses many of these conventions when making a thriller:
-Quick cuts/camera angle changes
-Tense music (often strings)
-Dark/dull lighting
-Use of shadows
-Sympathy towards victim
-Hand-held camera
-Characters may dress in dark colours
-Close-up of the characters face to show emotion of anger/revenge/fear
-Large, threatening weapons for props
-Colour effects (e.g. red indicates danger)
-Element of surprise, expected and unexpected
