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.

In the book, D'Artagnan doesn't actually become an official Musketeer until quite near the end, and we make quite a big thing about that. I won't give too much away, but when he finally does make it, they're not going to make it easy for him. That never changes.

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 BBC came to me and they wanted to adapt the book [Three Musketeers] again, in the straightforward way, and I said no to that. I didn't want to do that. But what I did want to do was have a real look at the adventure genre because I thought it was ripe for reinvention.

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 situation that women were in, at the time, was something that Dumas doesn't really go into, but it's a great subject to look at. It's a great genre because you can do a lot. Sometimes in thrillers, you can really explore things, and it's the same in this genre.
