I had never done anything with blue screen before, or prosthetics, or anything like that. Lord of the Rings was like stepping into a videogame for me. It was another world completely. But, to be honest, I basically did it so that I could have the ears. I thought they would really work with my bare head.
Actresses can get outrageously precious about the way they look. That's not what life's about. If you starve yourself to the point where your brain cells shrivel, you will never do good work. And if you're overly conscious of your arms flapping in the wind, how can you look the other actor in the eye to respond to them?
