Developing a script for our trailer

Whilst developing the script for our trailer, we came to realise that most of our trailer, if not all, would involve no diagetic sound. All our trailer would contain is non-diagetic music to keep our audience intrigued. Therefore we did not need to create or deliver a script to our actors. Also we felt that without diagetic sound, it would add a sense of mystery to our trailer and make our audience want to know more.
