"Godzilla Minus One" won the Oscar for best visual effects, with the award going to Takashi Yamazaki, Kiyoko Shibuya, Masaki Takahashi and Tatsuji Nojima.

The team behind the fan-favorite Japanese film took to the stage to accept the trophy from "Twins" co-stars Arnold Schwarzenegger and Danny DeVito and paid tribute to one of the film's producers, Shūji Abe, who died in December, and who they said was "lost too soon."

Other nominees in the category included "The Creator," "Guardians of the Galaxy Vol. 3," "Mission Impossible - Dead Reckoning Part One" and "Napoleon."

Robert Downey Jr. won the Oscar for best supporting actor.

The actor won the award for his portrayal of Lewis Strauss in "Oppenheimer."

The award was introduced by previous Oscar winners in the category including Ke Huy Quan, Sam Rockwell, Tim Robbins, Christoph Waltz and Mahershala Ali. They all shared words honoring each nominee before the Oscar was given to Downey.

"Thanks Sam, thanks fellas. You only flubbed one line," Downey joked during his acceptance speech. "I'd like to thank my terrible childhood and the academy, in that order. I'd like to thank my veterinarian -- I mean wife, Susan Downey, over there. She found me, a snarling rescue pet, and you loved me back to life, and that's why I'm here. Thank you."

"Here's my little secret. I needed this job more than it needed me," he continued. "Chris knew it, Emma made sure that she surrounded me with one of the great casts and crews of all time: Emily, Cillian, Matt Damon, Blunt -- it was fantastic. And I stand here before you a better man because of it."

Downey ended his speech by saying, "What we do is meaningful and the stuff that we decide to make is important," before thanking his stylist, entertainment lawyer and others.

This awards season, Downey's role in "Oppenheimer" earned him a Golden Globe for best performance by a male actor in a supporting role in any motion picture and a Screen Actors Guild Award for outstanding performance by a male actor in a supporting role. Downey and the rest of the "Oppenheimer" cast also won a SAG Award for outstanding performance by a cast in a motion picture.

Other nominees in the category included Sterling K. Brown for "American Fiction," Robert De Niro for "Killers of the Flower Moon," Ryan Gosling for "Barbie" and Mark Ruffalo for "Poor Things."

“The Zone of Interest” won the Oscar for best international feature film. Dwayne Johnson and Bad Bunny presented the award to the film’s director, Jonathan Glazer.

“El arte de cine es una lengua universal que habla a los hilos que nos unan juntos,” Bad Bunny said, which translates to, “Cinema is a universal language that speaks to the common threads that bind us together.”

Glazer took the stage to accept the award and said, “All our choices were made to reflect and confront us in the present, not to say, ‘Look what they did then,’ rather, ‘Look, what we do now.’ Our film shows where dehumanization leads at its worst. It shaped all of our past and present.”

“Right now, we stand here as men who refute their Jewishness and the Holocaust being hijacked by an occupation which has led to conflicts for so many innocent people,” he continued. “Whether the victims of Oct. 7 in Israel or the ongoing attack on Gaza, all the victims of this dehumanization -- how do we resist?”

Other nominees in the category included “Io Capitano” (Italy), “Perfect Days” (Japan), “Society of the Snow” (Spain) and “The Teachers’ Lounge” (Germany).

Scott George took the Oscars stage with the Osage Singers and dancers to perform "Wahzhazhe (A Song For My People)."

The song, which is from "Killers of the Flower Moon," is nominated for best original song.

"Killers of the Flower Moon," directed by Martin Scorsese, chronicles the series of real-life murders of members of the Osage Nation in 1920s Oklahoma, a period known as the Reign of Terror.
