Creating my poster

Having viewed many posters produced from big film releases and others that i have seen my class mates producing i have a good idea of what i want mine to look like. My idea is for the poster not to look to busy but for the image to be striking and get people to look at it and the release date of the film. This i believe is key for a small silm maker as reseach shows that people only look at poster for a few second and they only take in a little bit ofr the info that is on the poster. The image that i am going to put in my poster is going to be from the film and one of the main characters.
