The Academy Awards, commonly known as the Oscars, began on Sunday night in Los Angeles, with a first acting award for Brad Pitt for Quentin Tarantino's Once Upon a Time ... in Hollywood and a writing win for Nazi-era comedy Jojo Rabbit.
Parasite Director Bong Joon-Ho made history at the Oscars, with the film being the first foreign language film to win an Oscar. He is also only the second win the Oscar for Best Director for a non-English film.
Laura Dern picked up the award for supporting actress for her role in Netflix's Marriage Story while South Korean director Bong Joon-Ho picked up three awards for Parasite.
Joaquin Phoenix won best actor for Joker, delivering an emotional speech, and Renee Zellweger won best actress for Judy Garland biopic Judy.
Brad Pitt previously won the Oscar as a producer of 12 Years a Slave but this is his first acting win. Other winners include costume design for Little Women and animated feature film for Toy Story 4.
1917 picked up wins for sound mixing, cinematography and visual effects.
For the second year in a row, the ceremony was hostless. Dark comic thriller Joker led the nominations with 11, while Martin Scorsese's The Irishman, World War I epic 1917 and Once Upon a Time ... in Hollywood all had 10 nods.
Controversy over lack of representation
The awards were presented amid ongoing controversy around the lack of representation of women and people of color.
Greta Gerwig's Little Women was the only movie directed by a woman that received a nomination for best picture, although Gerwig was snubbed in the all-male best director category.
Actress Natalie Portman arrived in a dress embroidered with the names of female directors not nominated while opening singer Janelle Monae called out the lack of female representation during her song.
Meanwhile, actor Chris Rock was quick to point out that only one person of color had been nominated in any of the four acting categories — Cynthia Erivo for Harriet.
Animated short Hair Love, which features a young black girl's father learning how to do her hair, picked up an award, with creators Matthew Cherry and Karen Rupert Toliver taking the opportunity to say "representation matters."
