1) Devil Mask: The devil mask that Muerte uses is actually from another series showing on some channel in the cable TV world. I had never heard of it until I looked up the mask. I really don't remember the title. But I researched the mask copyright just in case and sure enough it was created for that series. That is why you see the constant blur on it. I hope it hasn't been completely unpleasant. For me, I think it's kind of cool to have that mystery of Muerte further compounded by the blurred view of him wearing that mask.
