Paranormal Activity 4 has arrived on DVD and Blu-ray and we've been given a weirdly wonderful graphic to show just how scary it is compared to other movies.

It has been five years since the disappearance of Katie and Hunter, and a suburban family witness strange events in their neighborhood when a woman and a mysterious child move in.

Remember to turn all the lights on because this franchise gets tenser and tenser, from exploding cupboards to young women being pulled from their beds as they sleep. There may be something weird going on but sometimes it's better to ignore the bumps in the night and retreat under the covers for a little more safety!
