Ah, Best Production Design. It was about time the name was changed.
Previously known as “Best Art Direction,” the award doesn’t cite a movie’s art director. Rather, it recognizes both the production designer, who is in charge of the set designs and the overall art department, and the set decorator, whose responsibility it is to fill up those environments with accouterment that truly brings them alive.
The Designers Branch, as it is now known, votes for the nominees in Best Production Design. It also contains the costume designers, making the branch responsible for two of the Oscar categories, like the sound branch. And while the category’s name has changed, the rules have not, so branch's past behavior provides helpful guidance in handicapping this race.
