I first began work on this film ten years ago, which is an indication of how long films can take to reach audiences; if they ever do at all. Jonathan Cavendish, its producer, told me the story of his parents, and I knew at once I wanted to write it as a screenplay, even though at that point there was no finance available. I was happy to embark on the project with Jonathan, and let it lead wherever it might. The result is now completed, and has proved to be one of the best experiences of my life as a screenwriter. Not since 'Shadowlands' has a work of mine been translated to the screen intact. I'm lucky to have fallen into the hands of a director as wise, as skilled, and as remarkable with actors, as Andy Serkis; and I'm lucky to have been graced with two lead actors of the talent of Andrew Garfield and Claire Foy.
So I love the film, and find it moving every time I watch it. But of course I'm aware that there are many who don't much like it.
