There were a number of people who helped me get there, and the one I always mention is Michael Byrne, the great master swordsman and brilliant stunt double.
To start your life as a character of 120 years when you are in your late thirties, and then go back in time about 20 years later to play the same character who is your own age then, its very complicated, but very interesting.
I'm the blackest villain of all time.
When George asked me to be the prequels, it was the same kind of meeting - it was very short and to the point. It was nice to see him after a long time, and we met in a hotel room.
But he did say that the character would be on the sidelines in movies One and Two, and move into the middle with number Three, but I didn't realize he would move in with quite such a bang.
For me it's even more interesting, because my character comes out of the shadow. It's a chance to really act emotionally, because the situation is an extreme one.
It was a scene I was really looking forward to, and one that I embraced, and when we were filming it, George got closer and closer and closer with that camera - he was practically up my nose for the final shot. So I knew it was a moment that I had to do my best to get right.
Consistency is very important when you're making films.
