The nature of a film like Hemingway & Gellhorn and is that the... Going into that process, where you know you have to go from a standing start, so to speak, to a finished film in less than seven months... Usually, a film like that would take, certainly, a year, from starting shooting to the final answer print. Sometimes 11 months. Sometimes 13 months. Sometimes 15 months. But seven months is on the short side. But not for television. But this had... The challenges of this were that – of Hemingway & Gellhorn – was that there was this level of technical difficult challenge on top of everything else that goes on. And then you see certain opportunities that you have to take advantage of things that emerge out of the whole process.

One of the things about the film is that it travels back and forth from black and white to colour, to a kind of, let's call it, 'Lumière' colour, sort of turn of the century, early version two-strip colour, where things are not completely fleshed out. And we had filters that we evolved in the process to... For each of these stages, and sometimes even more. And I would discover things that were new to me as a result of this process, which is a scene, for instance, in the trenches during the Spanish Civil War, where Hemingway and Gellhorn are there as reporters, and the battle is going on all around them, and then at the end of the battle, they are... they're still alive, they're not wounded, and a romance is blossoming between them, and we're making the transition from the black and white archival footage back into a more high-definition image. And what we wound up doing was taking that... Even in the... even when we were not looking at them, buried in this archival footage, we still maintained this subdued colour, as their relationship was... They were kind of feeling each other out. And then at the moment that they realised, 'there's something happening between us', then we were able to turn the colour up more. It's as if they began to blush with full colour when they realised that they... The possibility of some romantic something was growing within them.
