Avatar Poster
In this poster, very little is revealed. All we see is half of a blue face. But, in not telling us much about the film, the poster makes us want to see it; it has an element of mystery. This is a gamble, as the image doesn't guarantee that the film will be worth watching. This is why, at the top, it gives an example of a popular film that we may have seen, which had the same director. This says, 'The film you saw a few years ago was good and this one is by the same director, so it will be good as well'.
 We also see the name of the film, so we know what it's called and the website address encourages us to take a greater interest in it. The logos in the bottom right-hand corner tell us which organisations were involved, which does the same job as telling us what else the director has been involved in.
