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.

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.

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.

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

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 think the glue that held Fringe together was the relationships.

'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.
