First big surprise was the absence of Amy Adams from the Best Actress category. She seemed like a pretty sure bet. The one other surprise was Mel Gibson getting a Best Director nomination for Hacksaw Ridge. Gibson hasn't been nominated since he won for Braveheart in 1996.
A few interesting facts
La La Land got 14 nomination which ties the record with Titanic and All About Eve. Both of those movies won Best Picture so it puts La La Land as the front runner. There are three movies that had 13 nominations that have lost Best Picture and those are Mary Poppins, The Curious Case of Benjamin Button, and Lord of the Rings: The Fellowship of the Ring. It is also the first movie in 3 years to get a nomination in the Top 5 (Picture, Director, Screenplay, Actor, and Actress). The last movie to be nominated for all 5 was American Hustle in 2013. Only three movies have ever won all five (It Happened One Night, One Flew Over the Cuckoo's Nest, and Silence of the Lambs).
La La Land is also the third musical to be nominated for Best Picture that was not based on a previously material. The other two are Anchors Away and All that Jazz.
Barry Jenkins becomes the first black man to be nominated as director, screenwriter, and producer for Moonlight. If he wins he would be the first black man to win. Only 3 have been nominated previously (John Singleton, Lee Daniels, Steve McQueen).
Kubo and the Two Strings is the second animated movie to ever be nominated for Best Special Effects. The Nightmare Before Christmas was the first.
O.J.: Made in America was made as a miniseries on ESPN but after playing in a few festivals it got enough support to earn an Oscar nomination for Best Documentary. At 7 hours 47 minutes it's the longest film ever to be nominated for an Oscar.
Tanna is the first time Australia has been nominated for Best Foreign Language film.
