Twisted Fairytale movie posters

Above is a collection of fairy-tale movie posters which the stories have a twist. I have researched these posters because I want to develop my own poster based on a twisted horror/thriller theme. This is because I feel like it would be interesting to see how it develops and it would make a poster eye-catching. When looking at these posters they each give a dark creepy appearance and instantly tell you that the movie it is based on is going to be eerie and this would be appealing to that type of audience.
