The flub of Warren Beatty and Faye Dunaway's naming the wrong film Best Picture (La La Land (2016) instead of Moonlight (2016)) had never happened before in the Oscars' history.
The 7-hour documentary O.J.: Made in America (2016) is the longest film ever to receive an Oscar nomination.
La La Land (2016) tied with All About Eve (1950) and Titanic (1997) for the most ever Oscar nominations with 14. La La Land (2016) is the only of the three movies to not win Best Picture.
La La Land (2016) erroneously being declared Best Picture is actually the second time a presenter had announced the wrong winner during an Academy Awards ceremony. During The 36th Annual Academy Awards (1964), Sammy Davis Jr. was presenting the award for Best Adaptation or Treatment Score, but was mistakenly given the envelope for Best Original Score and announced Tom Jones (1963) as the winner. Given that the two categories had a completely different set of nominees and Tom Jones was not nominated, the error was recognized immediately and the correct envelope was quickly given to Davis, who announced Irma la Douce (1963) was the actual winner.
Re-recording mixer Kevin O'Connell received his 21st Oscar nomination in 2017. He finally won in 2017, breaking his streak on being known as "Oscars' biggest non-winner". He lost on all his previous 20 nomination.
