The movie promo posters are so classic! Check them out here. I had a hard time deciding which is my fave from the lot.
I like the way the swan and lady overlaps, and on the right looks like there's another swan. Reminds me of the old woman/young girl optical illusion, haha.
The pained look on the face kinda attracts me for some warped reason. It feels like the soul is being sucked back.
I decided on this because it looks the most classic (the text area), there is a ballet pose and the arms on fifth are paralleled by the wings on fifth.
