Drafting and planning - Inspiration for film poster

I have 2 ideas for Film posters. This film poster on the left has various elements which i want to create. My film poster will have the main actor looking at the camera (direct mode of address) with a Devil like figure over his shoulder creating an element of suspense.
The next idea i have is having the having one of the victims standing there with light beaming on him and the shadow in the background of the devil. similar to the film poster on the right.
