Radio Trailer Research

Advertising a film through radio is a good way to hit a mass audience due to its accessibility. A successful radio trailer should engage listeners without visual effects, therefore should include voice overs, sound effects, an interesting slogan and information such as cinema release date, certificate and reviews.
For our own radio trailer, we will incorporate dialogue from our film as well as a voice over. The dialogue will interest the audience as it will be of our actor screaming and yelling 'who is it' 'what do you want' to indicate the genre of a horror/thriller. The voice over will include the distributor, the name of the film, starring actors, dates, genre, certificate, reviews and where the targeted audience will be able to access the film. Non-diagetic sound will also be added from the film to the radio trailer to get the audience familiar with the genre and type of film. Diagetic sounds also include the squeaking of doors and stairs, slamming of doors and footsteps which will also be cut from our film and put into the trailer to create a suspense and tension, building up to the last part of the trailer.
I will be researching horror trailers specifically to find the conventions of radio trailers and to find how they market and interest listeners. Here is an example:

This radio trailer entwines voice overs, dialogue and intense music which builds up creating suspense for the audience. The turn-taking of the voice over and dialogue gives out vital information about the film and the incorporation of varying voices makes it more interesting for the audience to listen to. The sound effects of guns firing can also be heard throughout to show listeners the genre of the film, being an action thriller as stated by the voice over. Here, the voice over has included:

• The background of the storyline 
• Main actors 
• Genre 
• Name of the film 
• Cinema release date 
• Certificate 

In just 20 seconds the radio trailer have included everything the audience has to know to decide whether they would watch the film. The fast pace of the trailer represents the action genre of the film which is very attractive to listeners therefore helping the film to sell. Fast pace music will be used in our trailer when the intruder is seen, however slow paced music will be played for the first part of the trailer, which will gradually build up. We will then end our film with the name of the film to emphasise the title making it more familiar and eye catching to the audience, resulting in them more likely to tell friends about it and more likely to go see it.
