In terms of the movie business, being in a 'Lord of the Rings' has given me more interesting options as work.
Sometimes a scene works and acting is the easiest thing in the world and you don't have to do much of anything - just enjoy yourself and listen to the other actor. When it doesn't work, then every actor has different ways of dealing with the impasse. Sometimes you use memories from the past. Whatever. It depends from job to job.
Looking at acting, in the movies or the theater, and the way I like to look at it, it's just an extension of childhood play... Kids play and imagine in a very intense fashion and they don't need any director telling them, 'You really have to believe in it.' They believe in it completely.
I think every family is dysfunctional, and some manage to control it better than others.
