Another current poster used for the new Harry Potter 7 part 1 film. It is an extreme long shot of Snape and a medium shot of Harry, and personally in contrast to the other posters, this one shows a little bit more about what the may contain, because of the other posters being quite basic.
We can see from the light behind Harry's body and head, that it gives him a halo effect to show the audience that he is the protagonist, and he is the character that is going attempt or succeed in saving the reality around him. If we look in the background we can see the antagonist (Snape) hiding in the shadows, dressed in black, looking at Harry. This gives off the effect that he is the evil bringer, and the target or enemy that Harry has to face.
We can also see from this movie poster that there are nothing but dark and ill-lighted colours used, which tells the audience that Harry will be encouting several problems, and that things will not be positive in this film.
