Human beings, we have dark sides; we have dark issues in our lives. To progress anywhere in life, you have to face your demons.

I remember when I read Walter, for example, six years ago now, I said, "This is the role for me." I said that to my family. There was something there that I knew was absolutely right, and that was just based on the character. That's when gut instinct comes into play. I know there are certain things I won't do.

I don't know how I absorb things, but I do. I just absorb them. I don't over read the script, and I don't really ever spend much time learning it.

[on playing Walter] It was wonderful to be able to play a character who had so many colors and who was able to play comedy, to play incredibly vulnerable, which he did a lot of the time, to play the love story, and to play the relationship with the son, which is quite unusual. That's a gift to me, as an actor. It was like everything you could possibly hope for, over five years. So, I was a very lucky actor.

I'm a character actor, so as a character actor, I'm always looking for something interesting.

I don't know where the line is. I don't know how much of myself is in Walter. There's got to be a bit of him there.

There's a certain pattern that exists with geniuses - an eccentricity, a lack of social graces and an inability to really communicate with mere mortals.
