I have a whole spreadsheet tracking this very thing, Tee.
Writing, the last couple of decades, has overtaken acting, directing, and editing in importance.
The last film to win Best Picture without an writing nomination was Titanic in 1997. Before that, it was The Sound of Music in 1965.
Directing misses were Green Book in 2018, Argo in 2012, and Driving Miss Daisy in 1989.
Acting misses were Parasite this year, Slumdog in 2008, Lord of the Rings in 2003, Braveheart in 1995, The Last Emperor in 1987.
Editing misses were Birdman in 2014, Ordinary People in 1980, Annie Hall in 1977, and A Man for All Seasons in 1966.
For all-time purposes, Directing is still number one mattered in 87 of 92 cases (94.57%), Writing is second with 85 of 92 (92.39%), Editing is third with 76 of 86 (88.37%), Acting is fourth with 80 of 92 (86.96%), and a distant fifth is Cinematography with 57 of 92 (91.96%).
In the last 5 years, both editing and writing have been required followed by acting/directing in a tie.
In the last 10 years, writing is top, followed by editing/acting in a tie, and then directing.
In the last 15 years, writing is top, followed by editing, then acting/directing in a tie.
In the last 20 years, writing is top, followed by editing, then directing, then acting.
In the last 25 years, writing/editing are top, followed by directing, then acting.
In the last 30 years, writing/editing are top, followed by directing, then acting.
So, essentially, although directing was the dominant requirement for most of Oscar history, writing and editing have both supplanted it and acting remains a third/fourth requirement in recent years.
Having all three of acting/directing/writing was once dominant (83.70% of history), but that number has slowly cratered such that in 30 years, it was down to 80%, 20 years to 75%, 10 years to 70%, and in the last 5, it's been 60%.
Being the most nominated film was also a more dominant trait with historically 61.96% of Best Picture winners being most nominated. That number has plummeted to 56.67% in the last 30, 40% in the last 20, 30% in the last 10, and an anemic 20% in the last 5. This means that it's more likely that the most nominated will lose than the most nominated will win.
Even worse, double-digit nominations, other than in the first decade, were more likely to win Best Picture than they have been in the last few years. The Shape of Water, The Artist, The King's Speech, Slumdog Millionaire, The Lord of the RIngs, and Chicago are the only ones in the last two decades. The average nominations count of the last 5 years is 7.2 with Shape of Water the only film in the last five years to pick up more than 6 nominations.
In terms of winners, historically, the most honored film of the year has been the Best Picture winner with 79.35% of all-time winners. That number is down to 40% in 5 years, 50% in 10, and 70% in 20.
With the decrease in nomination counts of Best Picture winners, the percentage of wins, while historically below the number of films with most nominations or most wins, is now more dominant, but still down. in 20 years, it's 53.32%, 10 years is 44.47%, with an uptick in 5 years at 48.15%. These last 5 years is the first time those positions have been reversed.
Anyway, thank you for coming to my TED Talk.
