Psychoanalytic theory in film - Case study

Psychoanalytic theory originally was the idea that the brain can be separated into four sectors, each with conflicting roles. The conscious, unconscious, ID and the ego. The conscious follows the 'norm' considering societies views it represses the urge to act out of the acceptable. The unconscious holds our unspoken and unaware to even ourselves fear, wants, and desires. Some not logical, or considered 'right' it only becomes active in our dreams. The ID acts as your instinctive, and is the part of you which seeks gratification. Your ego works with both your concious and unconcious, it is the balanced part of your brain. Seperating real and unrealistic and right from wrong. When this applying this theory to film it challenges how much we can compare films to our, or, the directors unconsious mind. Are films shaped by the unconscious, like analouges to dreams? Or is it dependant to the individuals perception. Does the audiences unconscious identify with the characters, creating an unexplainable feeling toward them, whether it be, fear or fixation. And was this a conscious decision from the director to that group of audience?
