Ideas for a viral advert

Some ideas for virally advertising my film would be;
- Radio Trailers
- Video clips
- Links on social media (Twitter, Facebook, Instagram)
- Posters
Just general advertising techniques that we can use for as little cost as possible and to get the word out about are film to as many people as possible the more people that know about the film the bigger the chance of more people going to watch it.
Radio Trailers are a good way to get out to a mass audience but people arent often concentrating too much when listening to radios so would have an attention grabbing trailer or they would have already know of the film for it to get there attention.
Video Clips on social media would be my personal favourite technique for virally advertising the film. Get the actors of the film to make a silly behind the scenes of how some shots were done post it on social media, then the audience will watch it and feel a certain bond with them and are likely to want to watch the film. This would obviously be completely free aswell and could potentially reach a mass audience with the right backing.
Posters/ Billboards old way of advertising but effective slap the film poster on main roads/sides of buses does reach a mass audience but would cost alot so would need to be a big budget film, which our film is not.
