10 Hidden Details That Make Horror Movies Even Scarier

10. Inside - The Killer Walks Straight Into The House

Inside is not subtle. This is a horror movie where characters get their faces blown apart and a pregnant woman is stabbed with a pair of scissors. The fake blood used alone is probably enough to fill a small lake in the countryside.

Still, there is one chillingly subdued moment early in the movie where the villain of the piece makes her way inside the house of the woman she'll torment for the rest of the run time.

At one point, protagonist Sarah phones the police after being accosted by a strange woman knocking on her door. Unable to really help at this point as nothing criminal has occurred, the police take a statement and leave. Unwittingly however, they also provide the perfect opportunity for this woman to slip into the house.

That's because as Sarah and an officer sit on the couch discussing options, in the top left of the frame you can see the woman in black nonchalantly go upstairs, seeking out a place to attack later.

It's the casualness of it that's so chilling, and the fact that the anarchy to come could have been avoided with one quick glance.
