Since the introduction of the Best Supporting categories in 1936, there have been, to date, exactly 1500 Oscar nominations for acting, across 986 films. I used the Wikipedia & Oscar websites to gather the list of nominees, and was able to match in about 70% of the directors thanks to Bob Bourland's list of over 10,000 films complete with director. Sadly that list no longer seems to be on line or I'd link to it.
I got about another 10% of the list filled in by matching in names from the Best Director nominees, but the rest came from looking up the names of the directors for each remaining film on IMDb.com and copying the results into a spreadsheet. Not the greatest fun to have on a Sunday afternoon, but it beats cleaning the house. |
