This Sandra Bullock starrer horror movie was quite average in terms of the scare factor but the poster indeed is quite creative. Although you must have seen similar illusions in our site or on the web. But still, not all artists are able to come up with the inspiration in such a great manner. Of course the picture is edited but that does not snatch away the beauty of the illusion created here. After all who expects a movie poster to be a real image without any touch ups or editing. Coming to the illusion, we are sure you can trace a face, probably a female face in the poster that has been made using the branches of the trees and birds.
