Taika Waititi‘s first Oscar is in the books!

The 44-year-old director — who wrote, directed and acted inJoJo Rabbit— won Sunday night in the Best Adapted Screenplay category, beating out fellow nominees Steven Zaillian forThe Irishman, Anthony McCarten forThe Two Popes,Greta GerwigforLittle Women, and Todd Phillips and Scott Silver forThe Joker.

“This is really light. This one’s light. It’s supposed to be heavy,” he joked upon accepting the award.

Waititi then gave a sweet shoutout to his mother, thanking her for giving him the inspiration to make the film.

“I’d like to thank my mother. I don’t know where you are mom, I lost you, hours ago. Thank you for being my mother and … for giving me the book that I adapted. This film wouldn’t have existed without you doing that.”

“This is really great,” he said. “I dedicate this to all the indigenous kids all over the world who want to do art and dance and write stories. We are the original story tellers and we can make it here as well.”
