The location we have chosen to film our thriller already has a very good natural light therefore no additional lighting is neccesary. The lighting will be dark but not so dark that the camera won't be able to focus on the fine details. This style of lighting will help to conceal the face of the villain and will help to add to the mystery and tension of the thriller opening. We need to make sure that the victim is shown in a little more light than the villain because this will help to show vulnerability which is often present in thriller films. 

The only sounds that we will want to keep from the actual filming (diagetic sound) will be the sound of the gun being loaded and possible the sound of footsteps, especially where the footsteps will be crunching on broken glass. We will therefore be adding non-diagetic sounds when editting the film opening. We will want to add a heatbeat sound throughout the opening as well as a music based soundtrack. These will have good effect and will help to add to the tension and build up of the film therefore increasing the climax.
