Suddenly, after years of television being the poor relation and film being everything, it now feels like film is a conjuring trick. It's like, "Oh, my god, how are you going to do that in 90 minutes, as opposed to eight hours?! I've got so little time to do this!" It becomes an art form, in itself. Doing both helps you do each one.

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.

I always thought it would never happen. And then, it became possible. In between commissions, I wrote it as an original screenplay [Allied].

Sometimes if you're a director, you want to believe that you're great and capable at all aspects - the technical side, the lights, everything - but I'm not.

There [in Allied] was depicting London in the war, as well, and doing that in a way where you see something that you don't normally see, which is how hedonistic it was. In reality, that's what was going on. But, all of it worked.

It was great fun to do because of the central character. With The Girl in the Spider's Web, the girl is really the central character. She's the whole thing.
