I made a choice for myself that I would not play Captain Crais as one-dimensional. I played him as a person who was searching for something, who was troubled, who needed to solve certain problems.

I think that's come across. With various roles that actors play, [one thing I don't like] is that they are given a wonderful opportunity to play a fully rounded character and they make it one-dimensional. I don't think that's really exciting for an audience. The audience love to be intrigued, to be led along a path of really what is going to happen next.

There's a wonderful series called 24, and that's one of the best television series I've ever watched, because you don't know what's going to happen next. That was my brief that I gave myself right from the beginning.

With Pilot, I made sure that he was a navigator, whose sole responsiblity was looking after Moya, and then looking after everyone else inside Moya. In many ways, Pilot was also a captain, but at the other end of the spectrum.
