In this poster I particularly liked how the swan and the dancer are doing the same movement. It  gives the audience a feeling of connection between the dancer and the swan. 

This poster shows the two main characters in the movie. Brad Pitt is in purple and is represented as a ghost or dream it seems. It is obvious that there is a connection between the two. 

This one is similar in the fact that because bruce willis is upside down, it implies that these two are on two different time planes. They are connected but we aren't sure how yet.
