"Parasite."

The 2020 Academy Awards belonged to "Parasite."

The South Korean film won four Oscars, including the biggest prize, best picture.

It became the first foreign-language film to claim the award and the first South Korean film to win any Oscar ever.

Without you, our Korean film audience, we are not here.

Thank you very much.

Parasite —a dark comedic thriller about social classes, also took home best international film, best director for Bong Joon-ho, and best original screenplay for Bong and Han Jin-won.

Writing a script is always such a lonely process.

We never write to represent our countries.

But this is very first Oscar to South Korea.

Thank you.

Joaquin Phoenix won best actor for his role in "Joker."

His first Academy Award.

God, I'm full of so much gratitude right now.

He spoke passionately about injustice against people of all kinds, animal rights, and about our disconnect with the quote "natural world."

I've been thinking a lot about some of the distressing issues that we are facing collectively, and I think at times we feel or are made to feel that we champion different causes.

But for me, I see commonality.

Many of us, what we're guilty of is an egocentric world view, the belief that we're the center of the universe.

We go into the natural world, and we plunder it for its resources.

We feel entitled to artificially inseminate a cow, and when she gives birth, we steal her baby, even though her cries of anguish are unmistakable.

And then we take her milk that's intended for her calf, and we put it in our coffee and our cereal.

Renée Zellweger won best actress for her role in Judy, which explores the tragic career and life of actress Judy Garland.

It is the second Oscar of Zellweger's career.

Miss Garland, you are certainly among the heroes who unite and define us, and this is certainly for you.

I am so grateful.

Brad Pitt snagged best supporting actor for his role in "Once Upon a Time in Hollywood."

He used part of his speech to address President Trump's impeachment trial.

They told me I only have 45 seconds up here, which is 45 seconds more than the Senate gave John Bolton this week.

Best supporting actress went to Laura Dern for her role in "Marriage Story."

You know, some say never meet your heroes, but I say if you're really blessed, you get them as your parents.

I share this with my acting heroes, my legends, Diane Ladd and Bruce Dern.

"1917," the World War I drama many picked to win best picture, won trophies for best cinematography, best sound mixing, and best visual effects.

Other highlights included: Sigourney Weaver, Brie Larson, and Gal Gadot praising their fellow female colleagues ahead of the best original score award.

We also wanted to stand here together and say that all women are superheroes.

- True. - Yep.

Which went to Hildur Gudnadóttir for Joker.

She was just the seventh woman ever to be nominated in this category and only the fourth to win.

To the girls, to the women, to the mothers, to the daughters, who hear the music bubbling within, please speak up.

We need to hear your voices.

The music categories didn't stop there.

Best original song went to (I'm Gonna) Love Me Again in "Rocketman" by Elton John.

This was John's second Oscar.

There were also some surprises during the show, including Rebel Wilson and James Corden presenting the award for visual effects, dressed as cats in homage to box-office flop "Cats."

And the Oscar goes to...

But the biggest surprise—Eminem's performance.

Some were shocked, some were excited.

The 47-year-old rapper performed his 2002 hit Lose Yourself.
