fun fact: that head piece had a loose wire that kept giving him electric shocks and he just acted through it.

 ”Guillermo, the director, he builds these gigantic, practical sets and practical props… one of which almost killed me. I sort of had this like Honey, I Shrunk the Kids kind of contraption on my head… and we kept doing these takes, and I’m like, ‘Man, it’s just cutting into my ear, I’m not bleeding but it feels sharp…’

Months go by and I keep using this thing and my lab partner in the movie has to put it on and he turns to me and he’s like, ‘You do realize this thing is electrocuting you right?’ There was a little loose wire on it that every time it lit up, it was just sending an electric current into my body. So if I seem shocked in the movie, that’s why.”
