The DGA vs. the Academy: Introduction
Since pre-1970 DGA finalists often consisted of more than five directors, it’s obvious that the DGA’s and the Academy’s lists couldn’t fully match. In the list below, the years before 1970 include DGA finalists who didn’t receive an Academy Award nod and, if applicable, those Academy Award-nominated directors not found in the (usually lengthier) DGA list.
The number in parentheses next to "DGA" indicates that year’s number of DGA finalists if other than five. Source: IMDb.
