I really had no idea this existed I thought this was some ILM trick. But nope I looked close and saw a man leaning back and forth and I was wondering what was going on. I have to investigate any interesting subjects and I knew this is a um,…how do you say,…fake…! So,..what do ya know the coat is silver and in front of a projector screen,..there we go,..It’s a special reflective material
which makes the man leave the seen. A video camera trick records the real-life setting in the background of the person. The image gets on some sort of front projector, which then displays the scene on the reflective material. Maybe this video will give you a good idea of it.
