towerofterror.org said:The corridor scene uses an old theatre trick called "Pepper's Ghost" where an image is projected using a mirror onto glass (a variation of Pepper's Ghost as in the past, the images are projected onto a scrim(a thin, translucent screen)) to make the image look as though it's right in front of you when it's actually off to the side.
The corridor scene itself is a forced perspective. It is about 4 feet high in back and about 8-10 feet high in front. There is a diagonal glass wall in the middle of the hall. To the left of it is a projector room with a scene. That projector projects the ghostly figures on the screen and is then picked up by the glass, so you can see it. When they disappear the hall goes dark and the back wall, which is a screen with a projector behind it, projects the window coming towards you and crashing while that's happening the screen on the side of the hall slides away (not the glass). Then after the window crashes fiber optic lights turn on, on the sides and in the projector room. You can see the refection of them off the glass. Then that's it.
