I've been in a cemetery plenty of times at night, it was only foggy once, but it was foggy everywhere--not just the cemetery.
Why do they try making it look s00perscary by adding fog?
Because you don't know what is inside the fog.
Why do they always play suspenseful music climaxing in a sharp sudden noise when the person is going to be confronted with something scary?
That's never happened to me...
Because it's a fucking movie, they can do what they want.
They'd need to rent out or make the whole cemetery, so they fog it up so no one can see the backdrops. magician;
