I sort of hate the collage on white background posters. You know the ones. You have several pictures that are basically scenes in the movie arranged together over the white background, generally using some sort of ragged edge around the pictures in order to make it look even more like a collage. This is a very common approach to posters, especially for light ensemble dramas and comedies. It can work well, but it generally doesn’t because you end up with several images of actors without any context associated with them.
On the other hand I do like the heart made out of the pages of the book. It’s related to the movie’s story and its a nice, interesting image. But the poster as a whole is still very bland.
