CAMERA ANGLES

STORY

Film noirs tend to have unusually convoluted story lines, frequently involving flashbacks and other editing techniques that disrupt and sometimes obscure the narrative sequence. Framing the entire primary narrative as a flashback is also a standard device. Voiceover narration, sometimes used as a structuring device, came to be seen as a noir hallmark.
Crime, usually murder, is an element of almost all film noirs; in addition to standard-issue greed, jealousy is frequently the criminal motivation. A CRIME INVESTIGATION by a private eye, a police detective (sometimes acting alone), or a concerned amateur is the most prevalent, but far from dominant, basic plot. In other common plots the protagonists are implicated in heists or con games, or in murderous conspiracies often involving adulterous affairs. False suspicions and accusations of crime are frequent plot elements, as are betrayals and double-crosses.
