So I remember this movie where there a bunch of people in this house, kind of younger people, mid 20”s, and they have set up cameras in all different rooms of the house. The house may be having renovations done? But all of these like 5 friends are there and dark things start happening, people start dying, all filmed from the perspective of the cameras. At one point they may pick a camera up and go outside? But they come back, finally after everyone is dead, they cycle through each camera, showing the house and all the people, and then everyone stands up, it was all an act, they all give each other high fives and congratulate each other on a good show.
