Film noir is a genre possessing a rather vague physical description. This is due to the fact that it is hard to formulate words for a specific feeling that is generated. Generally, it can be characterized as having a dark, mysterious plot, often involving a narrator, femme fatale and obvious sexual tension. When these elements are combined artfully, it creates an atmosphere that is filled with suspense, drama and emotion. The men and women who star in these films, often bring the depths of their characters to life, showing the flaws that exist within human nature.
