Here's a clip of the stacking chairs from Poltergeist. This is one of my favorite scenes. It is so brilliant in regards how the chairs were rearranged in a perfect configuration. The camera panned to JoBeth Williams for one long take. When the camera panned back, it was as if they had been stacked by the ghosts. What happened was the crew switched the chairs with ones that were in configuration.
