The sheet covering Paul Coleman (the body) was hard to breathe through due to it being covered in dried corn syrup used as fake blood. To combat this, a mask was built with a dust mask stuffed with a long plastic tube coming out near where his feet were. Not only did this allow him to breathe normally, he was also able to slow his breaths so that he didn't look like he was breathing on screen. This mask was dubbed by the crew The Elephant Mask.
