Psycho by Alfred Hitchcock.

Psycho.

This is a thriller about a woman, Marion Crane, who has stolen some money from her company and ran away. She comes across Bates Motel and meets Norman Bates, the owner of this rundown, solitary and unseen motel. She is murdered in the shower by his mother and he dumps her in the boot of her car in a river and claims that she never stayed to the detective who comes looking for her after she's been missing for a few days. He then gets caught out because she signed into a check-in book and reveals that she did stay however he says that they never spoke she just went to her room and left the next morning. His mother was meant to have died and she killed the private detective because hes seen her in the window. The sister and the boyfriend of Marion got police involved, telling them the whole story, and when they passed it off as though the detective had ran away with Marion they went to investigate at the hotel. There is a big twist at the end of this movie which I believe is very well though of by Hitchcock and makes the film very interesting.

In the shower scene we have a close up of Marion and in the background the curtain with a shadow. This shadow represents a musky figure, only the outline so we see no detail of a person. This creates tension and a thrilling image. There is the sound of running water, which is a diegetic sound representing the shower, which is a calm and relaxing. Then we have a non-diegetic sound of spine chilling music when the figure opens the curtain to reveal a woman with a knife in her hand. This creates a sense of danger. The characters facial expression is shown in this image and shows terror. 

Norman Bates is given a freaky look to match the characteristics of him. The character is given this gruel smile which makes us feel uncomfortable and uneasy, which is also what he seems to be when we first meet him at his Motel. 

I believe that this film is a very good one and is one of Hitchcock's finest, certainly the most thrilling.
