I'm truly grateful to the writers of Fringe for giving me that because, over the years, when I've spoken about the character with them, I've always felt that this would be the perfect way to end and complete his journey, and to complete the journey of this series, and they gave it to me.

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.

It might be different for people that are A-list actors, but a lot of us really look at what's offered to us and look for something that has some traction with other people. But, it's not like I read 100 scripts a week, and then pick and choose. Maybe some actors do. I certainly don't do that.

As actors, you don't actually need to know the future of the character. You just need to know the backgrounds.

A lot of the times, roles are chosen for us.

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.
