Idea for a radio advert

We have been talking about ideas for our radio advert. One of the main ideas we all agreed on was to include the typical voice of a radio advert/film advert.
We did research on who voices this famous 'advert voice' and found out he is called Don LaFontaine. He's voiced over 750,000 television spots and up to 5,000 movie trailers.             

                       
This gave us a base idea of how we wanted our radio trailer to be, and we wanted to stick with the 'typical' trailer voice.
In our radio trailer we decided to name to title of the film, name to actors and to have certain parts of the film dialogue in it. To decide this, we had to pick out which bits we thought would be most successful and agreed to have the scream at the end of the film as a basis to make it apparent our film is a thriller. Something else we also agreed on was that we would use the same music we've used throughout our film on our radio trailer to make sure they link together.
