As an actor, you try to bring as much of yourself to a part to try and create a feeling of authenticity and emotional truth and resonance.
Acting is kind of difficult to intellectualize - it's a far more visceral experience. It's really hard to be able to think about and then employ these kind of esoteric notions of this person's backstory and try to weave it in somehow. It's just kind of impossible.
I don't go to movies, I don't own a television, I don't buy magazines and I try not to receive mail, so I'm not really aware of popular culture.
I don't watch the movies I've been in. I try to stay as little aware of the final product as possible, because my job doesn't really change.
When you take on a role you try to do as much as possible beforehand to get your mind into it. Just to prepare because it's a daunting prospect to go six months or whatever.
