Here are the actor/actress/supporting actor/supporting actress rundowns of the past 10 years. I'll be the first to admit that I'm cheating a bit, as some of these films (usually the ones in the bottom category) are films I never finished watching after getting bored/uninterested/pissed off at the films when they would come on HBO. The bold font denotes a winner that particular year. Again, I realize the list would be more effective had I gone by release year instead of ceremony year, but I caught myself too late on that one.
