Deciding on our thriller idea

We all discussed our individual ideas together and decided which to use. We all agreed on a thriller idea of a thriller set in the 1950's. We decided to use this one as it was someting different and was quite an original concept,  we felt it would be a good experience to film. We all thought that this idea was a strong idea and we could work well together as a group on creating it. We worked on a powepoint which we were going to pitch to our teachers, Matt and Simon. This consisted of the different ideas which we had created for what the actors should wear, the camera, lighting, sound effects and what we should include in the mise en scene.
