THE SUSPENSE

The director of the famous scene of the shower scene is Alfred Hitchcock, he use inncocent womans with palid faces, and the murderer is all of times a men. He plays with the position of the camera, for example, makes you like the  victim character, it put also the camera in a position that you can see the murderer is coming and you can see also the victim that is not conscious of the danger until the last second. It makes you tensioned and obligates your brain to transmite you the horror long time before of the event, it gets an very long period of time whit the horror in the public that is more efficient than the impact in one second.
