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.

Lord Of The Rings fandom was massive, worldwide, entrenched. Generally it had been part of the fans' life all their life, because they had it read to them as children; they'd become Tolkien students.

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.

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.

We often get pigeon-holed as a tough guy, or whatever else. I've been pigeon-holed as a heavy and serious, and almost a baddy, but not quite a baddy, over the years of my work in television, particularly.

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

Walter is incredibly complex. I do a lot of thinking about the work I do, and try to get the rhythms of scenes.
