Idea For My Research Poster

For my assignment for my research report i am required to make a research poster on photoshop. I have made the decision to look into film trailers. I want to see if it is possible to make one of my own. For it i will be looking into what it is about a film trailer that appeals to the audience. This will be researching different production trailers and what you visually see within them.

The reason I will be looking at trailers is because when it comes to promotion within the film industry trailers are one of the first visual things we see from the film. Without them it would be hard to generate a buzz around a film. It gives the audience a understanding about what they are going to see and its a way of pulling in an audience. Different genres will appeal to a variety of people, so i will look into what it is that draws in a crowd. Is it a brand of a film? Actor or Actress in the film? Storyline or special effects?

The research i do will then allow me to start a small trailer of my own. So my question is how to plan a film a trailer.
