Harry Potter and the Prisoner of Azkaban had a different aesthetic compared to the previous two films in the series. These posters were proposed as characters’ posters by the Art Department of the film, but they were never used. The idea was to present posteres with the idea that dark times are ahead, and that now everything will change. Notice that some characters as Hagrid and McGonagall were considered for the posters, and that Dumbledore’s makes a great contrast being mostly white against the other ones which are mostly dark.
In the end, this close-up posters were never used and they decided to go with full body posters for the characters. However, the style of doing a light/dark constrat were used in other posters in which they combine up to three characters, as you can see below.
