From what I've gathered from Google, the guy doing it is Derren Brown, some hypnotist type, and is from his tv show where he pulls this stuff on people... as for the guy going into trance, I'm not sure but I remember reading that flashing specific light frequency can do that to someone, similarly to shows like Pokemon putting little kids into epileptic seizures.
Would have been funny if the started using the gun like a club when the zombie moved into his swinging range. I think the experiment would have went better when the zombie actors started dropping from head trauma...
The poor guy is so scared he doesnt even realize that the window doesnt shatter when he fires at the zombies behind it.
Anyone have ideas how they did the gun stuff?...those are clearly blanks, but how do they make blood stains on the zombies?
