'Fringe' is essentially a love story, so the scenes where Walter had close connection with Peter, but also with Anna's character or Jasika's character, were very special to me.

My last two characters have been Denethor and Walter Bishop. Both will be hard acts to follow. That sits in the hands of my managers, at present. I just have no idea what's going to be offered to me.

I was a theater man, so I was never in the situation of being a handsome Hollywood leading man, and then having to age.

You're always working with the relationships. It's pretty demanding, but then again I love that.

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.

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.

Over the last 25 years, since a lot of science writing became accessible to layman, I've become quite a consumer of science. As a child, I wasn't streamed into science, and I regret that now.
