Evil Dead - Swing Slip-Up
This is when they arrive at the cabin. You can hear that thumping noise from the swing on the porch hitting the wall. When the car pulls up, you can see the swing making the sound as it hits the wall, but it dosn't seem to be hitting the wall, just swinging left to right without hitting it. Also when Scotty moves towards the door you can see the swing is hitting the wall.
