"The most important keyword to me was ‘train’ and the structure of the narrative reflects that. It’s simple: Curtis travels from the very last section of the train to the front. So the different carriages represent different stages in the story – every time you enter a new car, it’s like a new world that the characters are experiencing."
[The interesting thing though is that its a love story but you guys barely touched through the whole thing] I think that’s the best part. I think it’s very lifelike, the story. Sometimes you meet these people in your life and it’s not meant to work out but they change you for the better. And that actually sometimes the strongest love can be someone you never touched. – Cristin Milioti
