Trailer research

There are many films that are around in the film industry at the moment that are of the same genre as ours. Finding advertising for this was easy and helped with plenty of ideas for our radio advert. The only problem was we couldn't find examples of film radio trailers anywhere online, but we did hear a few on the radio when we were doing this. We had to use video trailers instead to learn about the conventions. We need sound that will signify emptiness and gloom and sounds that will scare. We also need a voice over and dialogue from the film.
