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

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

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.

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.

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.

What I've observed is that television in the last decade has increased to something that's almost unrecognizable. They are feature films. That's a huge shift, and it's something the audience expects. They still may want to watch their half-hour sitcom, but when they watch scripted drama, they expect the standard.

I'd never done anything that required a five-year commitment. To build a show that seems to have kept the imagination of the world so much was a bit otherworldly.
