What's Important When Thinking About When Creating a Film Poster?

This video is one of the things I watched in order to gather research on how to make an effective movie poster...

Getting the image right
- Not giving too much away
- Attracting peoples eye so they want to go see the film
- Informing people what actors/actresses are in the film
- Informing people who was the directors etc who created the film
- Using the space well and not overcrowding the poster with text
- Using colour well, not too much or too little
- Making sure a good font is used
- Make sure ALL important information is on there
- Contrast between the text and picture
