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.

Working in television is very hard. I think people know that.

I find science really sexy and, at the time that I was a school kid, it certainly wasn't.

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.

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.

I think the glue that held Fringe together was the relationships.

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.
