Oscars: 'Parasite' wins best picture

The Academy Awards, commonly known as the Oscars, took place on Sunday night in Los Angeles, with the South Korean dark comedy thriller Parasite winning four awards, including best picture.

The night also saw a first acting award for Brad Pitt for Quentin Tarantino's Once Upon a Time ... in Hollywood. Pitt previously won as a producer of 12 Years a Slave, but this is his first acting win.

The award for best adapted screenplay went to New Zealander Taika Waititi for the Nazi-era comedy Jojo Rabbit.

Laura Dern picked up the award for supporting actress for her role in Netflix's Marriage Story.

Parasite also won the best director award for Bong Joon-Ho, as well as original screenplay and international feature film.

Joaquin Phoenix delivered an emotional speech after winning best actor for Joker, and Renee Zellweger won best actress for the Judy Garland biopic, Judy.

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. The 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. The Irishman failed to win a single award.

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.

Natalie Portman arrived in a dress embroidered with the names of female directors not nominated. Opening singer Janelle Monae called out the lack of female representation during her song.

Meanwhile, the 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.

The 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."
