A few of these years had multiple films to choose from for sure. No Blade Runner, Empire, Moon, They Live, Escape from New York, Warriors, Godfather, Full Metal Jacket, Dog Day Afternoon or Platoon.
1984 was a particularly good year - the Martian year wasn't - while not a dud, the only film that's not an all time favorite.
Directors - Rob Reiner - twice, Cohen Brothers - twice, Kubrick - twice
