The story of James Delaney is also someone who very deliberately presents himself as an individual and plays nations against each other, plays the East India against the Crown, all of those sort of overwhelming concepts that ran the world at the time.

What happened was I was invited to meet Tom [Hardy] to discuss a project that he had in his mind about an adventurer who returns to England from Africa with secrets and with a history, and the original idea was set some 80 years later than it is now. But in the conversation I really took to the idea and I'd wanted for a while to set something in 1830 and 1840 in London, so it struck a chord.

[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.

There's lots of different ways of writing stuff and lots of different mindsets to have, but I think when it's your own creation, it's more pleasurable because you have total control.

A commission and an original are two different things, and both have their virtues and vices. A commission is a bit more collaborative, in that you outline the story that you think should be told, and then you write it.

There were three options [in Allied], which were for [Bred Pitt] to shoot [Marion Cotillard], for them to escape, or for her to pull the trigger, which is a heroic act to spare him. When I was thinking about how it would end, a long time ago, I think I tried each of them to see, but two of them did not work.

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.
