Harry Potter Film Posters

The final 2 Harry Potter films had multiple posters each, one for each character.
Each films posters followed a certain theme, as you can see below;

Part I

Part II

As you can see, the posters for Part I gave away none of the plot whatsoever, simply showing the faces of the characters, whereas the posters for Part II show the damage and destruction behind the characters. The reason for this is that because the film was presented in two parts they had to do something to draw in audiences for the second part. All the posters show the emotions of the characters and seem very dark and foreboding which shows the theme of the film.
