My approach to D�Argo has changed considerably, mainly due to the physical freedom that I�ve now got from the make-up. Initially, I really couldn�t move within the suit, it was such a physically constraining piece of equipment. I couldn�t turn my head.

The real joke on set was that whenever D�Argo had to fight he had to reach back and grab his sword, and I could not grab my sword. It was physically impossible and it would drive me insane. Every time I had to do this we had to cut or find some weird way or some props guy would have to stand behind me and poke the end of my sword forward so that I�d be able to reach back far enough to actually grab my sword out.

I can now concentrate much more fully on the things I should be concentrating on, my relationships with the other characters and the emotional and psychological arc of the character. I don�t have to worry so much about the physical preparation.

Creating a new species, not only a new character, takes so much more preparation and thought than it would for a normal role in a normal film. Initially, I was really worried about how this person talks, how he moves, what his relationship to different things are and now that we�ve established those things and they�re solid we can let them go and just allow him to live and breathe within the world of Farscape.
