Whenever there's a new Christopher Nolan film out you know the closing credits aren't the end of the experience. Dissection of the themes and theorising over its high concepts are all part of the fun. And that's certainly the case with Interstellar, Nolan's latest, which has set the internet alight over the past weekend, although quite in the way we're accustomed to.
