2014 was, in my opinion, a pretty awesome year for production designers. There was an extremely rich variety of work on display, from trippy sci-fi to austere period pieces, and from autere sci-fi to trippy period pieces! It's a shame that only five can be honoured by the Academy (the guild has three categories over which to spread the wealth), because I can definitely think of at least ten worthy of a nomination.
And yet, as outstanding as so many sets were in so many movies this year, there's only one that has rightful claim to this award. And fortunately, that's the one on track to win.
