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.

I think main storylines are what always intrigued me, with those that were the relationships between the characters against whatever backdrop, whether it was in an ordinary universe or a universe in the future.

I always loved the challenge. When something new happened, I always used to get quite excited.

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.

We didn't know until really quite late in the piece how Joel [Wyman] would finish it off.

I suppose, when you start up in acting, you hope to be given challenges, and you always have dreams about the things you could do and couldn't do, but normally we get pigeon-holed a little bit, as we go on in our careers.

I didn't drop into the mannerisms of another version of the character, but I guess I was pretty alert to that.
