my research.

I've watched thriller movies recently, I really enjoyed Seven (1995), directed by David Fincher. there were several techniques used to create suspense and simply make the movie more gripping and interesting to watch.

• Pathetic Fallacy; used to create thrilling atmosphere. In most 'scary' scenes it was raining.
• Mise en Scene: -lighting: usually dark, -costume: I've noticed characters usually wear dark clothes.
• Sound: lound, digetic sound of rain, alarms, phone. Non-digetic, slow but dramatic music creates intrigue and tension. Accent: a lot of silence.
• Camera: mid shots+ long shots, not many close-ups. Probably to show audience what's around the characters.

Here's the trailer, enjoy! :
