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.

They're classic themes, which is why I think it's such a great story to look at again. The concept of being loyal to your friends, to the point where you'd even die for them, is a great subject.

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.

One of the problems of this genre is that there are cliches everywhere, and you've got to be careful and watch out. Our rule with cliches is to either gently acknowledge them and make fun of them, or do something else. Milady is, in one sense, a villain because she does bad things.

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.

It's not fundamentally different to any other genre, that action is a particular thing. Being able to do action sounds like it should be straightforward, but it really isn't. I always want the action to be witty. I don't want it to be merely routine.

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.
