Ideas For Thriller + Mise-en-scene + Camerawork

Idea 1 - Babysitter alone in house, stalked through phone calls.
Idea 2 - Wife plotting to kill her husband.
Idea 3 - Woman answers door to killer pizza delivery guy.
Idea 4 - Woman alone in house, goes to get something from pool house at the bottom of the garden. to find body.

At the moment my main focus is on idea 4. It is a very simple scene yet could be made very thrilling. Firstly, there is an establishing shot of the house. The house will be large and quite extravagant, highlighting how they may be quite wealthy. Then there will be classical music playing softly in the background, perhaps highlighting intelligence and higher class. Then the sound stops as the phone begins to ring in a medium close up with the camera focused just on the phone ringing. This will be used to shock the audience and to create suspense. She answers the phone, then hangs up. As she walks away, there is a shot of her from behind walking slowly turning towards the phone in suspicion.The phone rings again and this time its her husband. This highlights the fluctuation of suspense throughout the opening sequence. She talks to her husband on the phone, then looks out the window and through the blinds with a shot from her point of view and her looking through the blinds. Awaiting her husband to come home. Then there is a shot of the taps running. The bath symbolises how she is vulnerable and as she will be naked, its a sign of no protection. Whilst she is in the bath, she hears the door slam. Again another manoeuvre to make the audience jump in suspense. Then there will be a fast paced shot of a medium close up of her face, to see her reaction. She gets out of the bath to find no body home, there will be a tracking shot of her walking down the stairs. Although she is expecting her husband, she is still cautious when he doesn't respond to her calling him. She goes into the kitchen and takes a knife from the counter in fast paced jump cuts although she is tip toeing around the house. this will help to speed the scene up as well as keep the intensity. The knife symbolises how she is protecting herself from danger, or she is dangerous. She is only in her towel at this point. She is walking around the house and see's the back door open, there is a shot of the door open, then a shot of her looking out of the doorway the a reverse shot. We see her in several shots as she picks up the phone from the handset ready to call someone. This again subverts the stereotype of women within horror films being stupid by not just calling the police straight away. Then she goes to the back door and shouts her husbands name. There is still no answer. again creating more suspense. As she turns away she walks into the arms of the killer and there is an over the shoulder shot of the killer. she drops the phone to the ground and thats in a close up as we are able to hear voices on the line. Scene finishes.
