You can use the fun of the genre, but I also really wanted to come at it from the point of view of some really complex characterization. There was a lot that I wanted it to do, and I wanted it to be fun. It's fun, but it's not simple fun.

Richelieu was a great statesman, and like all great statesman, he was a very ruthless man. He's not cruel. He just does what he has to do. And in his own mind, he's absolutely right.

I think there's an element in Milady where she sees her own innocence in D'Artagnan. In the very beginning, she's using him in a pretty cynical way. When she gets to know him, she sees qualities in him that she recognizes and it's almost like trying to remake the past, but of course, it doesn't work.

On a simple level, you need directors who are good at action and can choreograph an action scene, but you need them to also have that sense of fun and that sense of movement and that ability to get the actors to really respond to the material in the way that you want them to. It's a very big thing.

You do see a few people and you are thinking of how that chemistry is going to work, but it's not really fair to put people who are auditioning together in a room. You have to make that judgement yourself, and that's partly where the casting director is so good. It was that blend that we were looking for.

You're always looking to make it a bit fresh. I want to make sure people are constantly surprised and interested, and we're always talking to the directors about that. It's a big challenge to find people that can do it.

The thing about villains is that villains always have their own logic, and they don't necessarily see themselves as villains. Richelieu is not a villain, in his own mind. He's doing what he needs to do.
