Scream opening

In the opening scene of Scream, there is a shot of the telephone which already shows the audience that the phone will be of importance in the film. When the girl picks up the kitchen phone she walks down the hallway and locks the door whilst talking on the phone and the camera is tracking her. It is following the action. When she stops by the TV, the camera zooms into her face to show her expression which allows the audience to identify how she is feeling.
Synchronous sound is used at the beginning of the film when the telephone is ringing. We can see the phone on screen but the volume of the ring has been increased for more tension so we know it is not just a background noise. There is a very important bit of dialogue between the girl and the person on the other end of the phone. The girl says " Why  do you wanna know my name?" and the person on the phone replies "Because i want to know who I'm looking at". This automatically makes the audience tense as they know someone is watching her.
She asks him "What do you want?" and he then replies "to see what your insides look like". We can now identify that the person on the other end of the phone is a killer.
At the beginning we can see that it is situated in a house because we can see the television and sofa in the background. The girl then walks into the kitchen where there is the cooker and fridge. etc. So we know she is in her house. She is dressed casually so we know she is probably having a night in and not going out anywhere. However the scene is shot in low lighting so we can identify that it is at night and dark outside. This adds to the tension for the audience.
