1Due to category confusion,
Barry Fitzgerald received nominations in both
lead actor and supporting for this same role, winning the latter award. To prevent this from occurring in the future, the Academy revised its rules so that if ever a single actor/actress was submitted in both categories for the same performance, they would only get nominated for whichever one had the higher overall percentage within that respective category.
2An anomaly occurred when both LaKeith Stanfield and Daniel Kaluuya received nominations in the supporting category, despite the former being campaigned for the lead race. This occurrence is likely a direct effect of the AMPAS enacted after Fitzgerald's brouhaha. Stanfield and Kaluuya received votes in both categories, but each of them had more nominations in supporting, and thus each made the top five nominees in this category.
