We often get pigeon-holed as a tough guy, or whatever else. I've been pigeon-holed as a heavy and serious, and almost a baddy, but not quite a baddy, over the years of my work in television, particularly.

We shouldn't be put out to pasture just because we've reached somebody's idea of retirement, which was certainly happening in Australia, and I think elsewhere as well.

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 love having played Walter because I suppose any actor brings a certain aspect of their own personality to their work, and I had a fairly broad canvas to paint on with the different versions.

You basically go in animation and it's all in the imagination. There aren't even pictures to look at. You usually go in there and work with whoever the director is to create this voice and this character.

[Fringe] was just about doing the job, or trying to do the job, properly. It was never a job that you could rest on your laurels. It was a very challenging 43 minutes of television that we were shooting, every week.

Particularly in the final season [of Fringe], when we were shooting seven-day episodes with a reduced budget and big special effects, the team was so polished, by then, that we were able to do it and, I think, with incredible results.
