The most famous horror movies scare the living daylights out of the audience with spine tingling scenes that live long in the memory - especially when the lights go out.

No matter how many times we are told that it is simply a film, a piece of entertainment, classic chiller's like Jaws can stop us getting into the water or in the case of Stephen King's 'It' make children's clown's petrifying.

However, the terror is only committed onto film and when the camera's stop rolling as these behind-the-scenes pictures show, the film stars and their crew relax and joke in unexpected and hilarious ways.
