This looks very irresponsible. I was helping some SCAD students with a film project and I volunteered to do a stunt. They had a professional firearms/explosives expert coordinating the squibs. And even though everything was done really professionally I got gun powder burns on my arms from the squib. But Uwe Boll won't let a child's welfare hinder his "genius"... asshole.
You should watch Bloodrayne 2. He actually had seven kids with real nooses around their necks precariously standing on chairs. He mentions in the commentary that they had security off-camera in case one of the kids fell off their chair.
SCAD student: "Yeah, that Cena_mark guy's really been pissing me off.. you could put too much powder in the squibs and we'll tell him it was an accident. Heehee!"
When I was this little bitch's age I used to walk FIVE MILES IN THE SNOW just for the opportunity to have half my skin singed off by shitty squib work.
