Watch: Minari star Yuh-Jung Youn charms with delightful Oscars speech

Minari star Yuh-Jung Youn charmed viewers around the world with her witty Oscars acceptance speech - some even called it the ceremony's very best moment.

The 73-year-old made history by becoming the first Korean actor to win an Academy Award for the Best Supporting Actress.

Receiving the award from Brad Pitt, whose company Plan B produced Minari, Youn began by saying: "Mr Brad Pitt, finally - nice to meet you." 

"Where were you while we were filming in person?" she joked. "[I'm] very honoured to meet you."

She also thanked her two sons for making her "go out and work". 

"This is the result, because mummy worked so hard," she said, holding the trophy up.

Youn then went on to call out people for mispronouncing her name.

"As you know, I am from Korea, and actually my name is Yuh-Jung Youn and most European people call me Yuh-Youn and some of them call me Yuh-Jung but tonight you are all forgiven," she said.

Youn plays feisty grandmother Soonja in Minari, a role which has won her several other awards.

But when accepting the Oscar she also praised her fellow nominees - Maria Bakalova, Glenn Close, Olivia Colman and Amanda Seyfried - for their performances.

"See, I don't believe in competition - how can I win over Glenn Close? I've been watching her so many performances," she said.

"So this is just all the nominees - five nominees - we are the winner for different movies, we play different roles. So we cannot compete each other.

"Tonight I'm here just because I have a little bit of luck, I think - maybe, I'm luckier than you."

Youn also dedicated her award to the late Ki-young Kim, the first director she ever worked with.

Social media users were thrilled to see her win the Oscar and delighted with her speech.

"Sarcastic, witty, classy and charming. I love how Youn Yuh Jung corrected everyone's pronunciation of her name," one person shared on Twitter.

British Glamour labelled her speech "the best moment of the night".

"Yuh-Jung Youn is the most charming, lovely, compelling woman to watch. I loved her in Minari and I adore all of her speeches. She is hilarious, beautiful, and incredibly talented. Congratulations to her on her much deserved Oscars win!" another fan wrote.

"What a treasure," added another.
