His, uh, hammer:
"It is a pretty impressive piece of equipment. It was quite heavy, so that helped with the stunts. If it was too light, you would swing it around like a toothpick and it wouldn't look impressive. When there is some weight to it and you have to physically use your shoulder and back, it gives you a sense of power. I got very comfortable holding it. When I did the earthbound scenes without it, I felt naked."
