The Halloween VI mask was sculpted ground up by the late John Carl Buechler and has a very unique "goblin" look, a one of a kind design for the franchise. There were lots of these pulled on set and their locations vary. During filming, there was lots of pressure due to the fact that this was the first Halloween to be made by a major production company. A lot of reshoots were done to satisfy the demands of the film company, resulting in multiple versions of the film. Story goes that as tensions grew during shooting (extensive reshoots, cutback on pay,etc...) an angry FX artist rubbed chemicals on the inside and outside destroying the masks.
