Ideas for an opening of a short film

Idea 1:
Working Title-A Dead Friendship/ The shadow puppet/ shadow of friendship/ the power of shadows
Genre-Drama
Narrative-It starts with a shot from the end of the whole film (one friend lays dead on the floor, the other stands looking at them), but cuts back to the start of the narrative, where the two friends are happy but argue on a regular basis.
Location-It is set in the drama room at school, that we will make to look like a cosy home.
Props-A gun for the start; blankets, cushions and rugs to make the drama room look homely; a phone; sofa like chairs.
Sound- Diegetic sound (talking on the phone); creepy music to put the audience on edge; dialogue.
Actors-Sian and I will play the main characters, we will need one extra for the phone call.
Audience hook-A question is posed about what happened that led to the death of one friend.

Idea 2:
Working Title-2 Detectives, 1 Case.
Genre-Crime/Detective
Narrative-Starts with a shot of a poser that says about a missing girl, cuts to two detectives viewing the poster, getting ready to take on the case to find the missing girl before a specific time or risk the girl dying. Shots are included with the mysterious kidnapper/murderer.
Location-Drama room in school, make to look like an office, but also dark alleyways.
Props-Tables; chairs; paper; trench coat and hat.
Sound-Mystery/crime theme tune from a TV show; dialogue; creepy music in the background.
Actors-Sian and I will play the main characters, we will need a couple of actors to play civilians, the missing girl and the kidnapper
Audience hook-The poster will pose questions about how she went missing and why.
