When I'm singing a song on stage, I hate hypocrites. If you don't put yourself in that lyric and emote and be what that lyric says that you are, then you're just going through the motions and you're being hypocritical. I just take that same approach with acting. I just take the dialogue and I emote it and become that. I use the same technic.
We humans are destined to live with our feet on the earth and our heads in the heavens, and we can never be at peace because we are pulled both ways.
