Themes to include in my film

My film must have certain themes and characteristics in it to be classed as a true film noir. Such themes/archetypes/visual iconography to address are:

• Truth seeking Protagonists escaping a past burden, traumatic incident or crime committed out of passion (LA Confidential, Brick)
• Femme Fatale, often linked to protagonist in tragic way (sexually seductive and often can hold their own in a male world (Brick, Black Dalahlia, LA Confidential)
• Corruption in the law (LA Confidential)
• The Criminal underworld (prostitution, drugs, murder etc)
• Low key lighting - different shades to show mood of character - most often only half the face is shown to increase tension
• Odd angles - most noirs use low angles to show the ceiling. This creates claustrophobia and unease, also paranoia. Characters towering from the ground gives them a dramatic importance 
• Moving Cameras - long shots of a camera tracking a character through a location often created tension with suspense. Adding foreground objects make the viewer more interested. 
• Flashbacks - most characters have troubled pasts so showing the audience this is better than just retelling it
• Rapid Dialogue - most Film Noirs, such as the Neo Noir "Brick" have fast and short exchanges of dialogue, much like an interrogation. These Noir dialogues are often full of "wise cracks". (Brick) 
• Voice Overs - these often are used to put the viewer into the mind of the protagonist and to identify with the narrator. (Black Dahalia)
