I want there to be dialogue between the two parents, but minimal so that the main sound is the tense music. The only things they should mention are the fact that their son / daughter is missing. i.e. 'She's late'.
For the teenager scene, I want there to be no dialogue, but only a soundtrack of some sort of pulsing beat, and distorted buzzing as if being unable to think when a short period of slow motion might be used. There will also be a lot of sound effects, to emphasis the opening of doors and running footsteps, as well as the stepping up onto the ledge.
I want to use lots of folly sounds with lots of noise to emphasis the chaos. I will open with a sound bridge of the soundtrack and running footsteps which will immediately get the audience concentrating on whats happening.
