For the sound categories, here's our annual reminder of the difference between Sound Editing and Sound Mixing. A big part of the Editing category is for created sound effects, so loud movies always stand a good chance. Mixing is how all the elements come together — sound effects, dialogue, the score, etc. This year, the same five nominees are up in both categories, which is a first since Sound Editing moved to five nominees in 2006. It feels like "Dunkirk" is the frontrunner in both categories, though if voters want to split things up to award something else and truly understand the difference between the two, "Baby Driver" might play spoiler for Mixing.
