The night full of firsts was highlighted by "Parasite" winning best picture, becoming the first foreign-language film to take home the biggest Oscar honor. But the ceremony wasn't all glitz and glam, as many stars at Los Angeles' Dolby Theatre used the spotlight to unveil deep-seated issues within the industry.
Here are the top moments from this year's unforgettable Oscar awards:
'PARASITE' DOMINATES THE ACADEMY AWARDS
South Korean film "Parasite" took home the prize for best picture during the Oscars shortly after the film won three other awards, including directing for Bong Joon Ho, best international film and best original screenplay.
The dark comedy is centered around income equality's wild influence on two families.
True to its name, "Parasite" simply got under the skin of Oscar voters, attaching itself to the American awards season and, ultimately, to history. The win was a watershed moment for the Academy Awards, which has long been content to relegate international films to their own category.
In a year dominated by period epics, "Parasite" beat out other best picture nominees like World War I epic "1917" and Quentin Tarantino's industry-glamorizing "Once Upon a Time ... in Hollywood."

BRAD PITT, JOAQUIN PHOENIX SEE NOTABLE WINS
Brad Pitt took home his first acting Oscar for his role as a stuntman in Quentin Tarantino's "Once Upon a Time...in Hollywood."
Pitt called the win "incredible," praising Tarantino for his originality as well as his co-star Leonardo DiCaprio.
Pitt told DiCaprio he'd "ride on his coattails any day, man."

Meanwhile, Joaquin Phoenix's win for best actor in "Joker" was his first time ever taking home an Oscar.
He's been nominated several times, including for "Gladiator" in 2001, "Walk the Line" in 2006 and "The Master" in 2013.
This award season, Phoenix has used his acceptance speeches to bring attention to issues within the industry. When he won in the leading actor category at the British Academy Film Awards, Phoenix challenged his peers to confront systemic racism.
His Oscars speech struck a similar tone.
"I have been a scoundrel in my life. I've been selfish, I've been cruel at times, hard to work with, and I'm grateful that so many of you in this room have given me a second chance," Phoenix said on Sunday. "And I think that's when we're at our best, when we support each other, not when we cancel each other out for past mistakes, but when we help each other to grow, when we educate each other, when we guide each other toward redemption. That is the best of humanity."

BILLIE EILISH, EMINEM TOP THE OSCAR PERFORMANCES
On the heels of making music history, newly minted Grammy winner Billie Eilish gave a soulful performance during the In Memoriam segment of the 92nd Academy Awards.
The 18-year-old also performed "Yesterday" by The Beatles alongside her producer-brother Finneas during the portion of the ceremony, which comes just days after the death of Kirk Douglas, one of the last surviving stars of Hollywood's golden age. Kobe Bryant, a 2018 Oscar winner for the short "Dear Basketball," was also included in the segment.

In an unexpected appearance, Slim Shady took to the Oscars stage Sunday.
Eminem's surprise performance of "Lose Yourself," a best original song winner in 2003 from the soundtrack to "8 Mile," left many, including Eilish, stunned.
The appearance was a big deal for the awards show after Eminem didn't perform as a nominee in '03. In a tweet after his performance, he referenced the 2003 show: "Look, if you had another shot, another opportunity... Thanks for having me @TheAcademy Sorry it took me 18 years to get here."

STARS CALL OUT SNUBS, FOCUS ON WOMEN'S ACHIEVEMENT
On a night heavily criticized over its lack of recognition for female achievements behind the camera, all eyes were on the women during this year's Oscar ceremony.
In the lead up to the 92nd annual Academy Awards, many in the film industry were outraged that all nominees for directing were, once again, only men. Actress Natalie Portman even made a red carpet fashion statement about the snubs, sporting a Dior cape with the names of all the female directors who weren't nominated in the category.

Throughout the night, presenters made opportunities to bring up the lack of gender equality in the show, or celebrate women's wins.
When Mark Ruffalo presented the nominees for best documentary feature, he noted that four of the films "are directed or co-directed by women."
When Sigourney Weaver, Gal Gadot and Brie Larson joined the stage to present, Weaver said "all women are superheroes."
