"We just worked hard to not just get things right and authentic, but also to make it consistent and visually right. For instance, there are colours that aren't in the film that would have been there in reality. I think part of the look of the film not only has to do with the way it's shot and lit, but also the lack of certain colours that give it a softness which really suits it because there's more focus on the characters. For instance, there's no yellow at all until we get to Miss Stubbs' flat at the very end."
