Key snubs included Jennifer Lopez for her role in Hustlers, Awkwafina for The Farewell and Little Women filmmaker Greta Gerwig.
Those three films won 11 awards in their respective years and Joker is now on course to do the same.
Robert De Niro, Taron Egerton and Adam Sandler also failed to secure nominations for their roles in The Irishman, Rocketman and Uncut Gems, respectively.
Joker has just been nominated for 11 Oscars meaning it’s in the running to match the number of wins achieved by record-holders Ben-Hur, Titanic and The Lord of the Rings: The Return of the King.
