Detailed Synopsis of the opening
A dark questioning room a man is siting one side of a questioning table his head hanging looking at his feet, a detective on the other. The tape recorder is going and the detective says "we've got for his murder so you may as well tell us why you did it" the man then looks up from the ground and says "officer i'll tell you what happened it all started with a beautiful woman"
Rough Treatment
My opening sequence will be in black and white this will help to give it a dark and eerie feel making it more thriller/noiresque I'll use close ups of the man as he looks and and of the detective (shot-reverse-shot) There is a going to be a single window in the room covered by a venetion blind creating the typical noiresque type shadows and contrast between dark and light To make my scene contemporary i'm going to use a modern day recorder like the police use to record interviews When the man starts to tell the police what happened there will be a flashback and then his voice over will start this is another noir convention. I will also use backing music consisting of dark minor chords but it will only be quiet in the background.
