I think things through a lot, so I probably use my head more than my heart. That probably comes through in my acting.
The hardest part of playing the villain was the prosthetics, because I couldn't really move my face as much as I wanted to, and yet I had to move my face a lot. If I moved my face in certain ways the prosthetics would come apart, so I could do a lot of eyebrow acting, but I couldn't do a lot of nose lifting, or the corners of the nose would pop out.
