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.

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.

With science becoming far more accessible to all of us, I've become a pretty avid reader and devourer of it. One of the objectives that I had working with Fringe was to get more people talking about it because it's such fun.

I loved playing Walternate because he was completely the same character, version 1985, and then it developed in such a different way, physically and mentally. So, to be able to play that, in the same television series, as playing the other ones was a fantastic gift for me.

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.

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

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