[The Girl in the Spider's Web] can't be anything other than a sequel, but a couple of books have been skipped, so it is different, in that sense. It's really taking a very strong central character and thinking, how do you execute this? It's quite different.

[Allied] meant to be a film that's a bit different. It's roots are in the '40s and '50s, and that sort of filmmaking style.

[Allied] got the attention of (director) Bob Zemeckis and Marion Cotillard. I'm glad I waited. If it had been made 15 years before, who knows how it would have looked, but it's got the best possible cast, director and everything. It's been fantastic. It was worth waiting.

It's great that the story [Allied] is set in the '40s because the '40s feel to it is completely appropriate.

I read more and more and I came across this character, Caroline Weldon. Sometimes in history, you find these people that no one would dare create. They're too mad.

You know that when you suggest something on the page, it's going to be there, plus more. It's a great luxury to know that you don't have to push it. You just lay it out, and it will be there.

I spoke to Tom's [Hardy] manager and said, "While we're talking about Taboo, do you mind if I also mention this film project that I've got, which is called Locke, and I need Tom to play the lead." And we spoke about both in that meeting and in the end the deal was that I would do Taboo if he did Locke and vice versa.
