'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.

I'm a character actor, so as a character actor, I'm always looking for something interesting.

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.

I didn't drop into the mannerisms of another version of the character, but I guess I was pretty alert to that.

Mars tugs at the human imagination like no other planet. With a force mightier than gravity, it attracts the eye to the shimmering red presence in the clear night sky.

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