"Poor Things" won the Oscar for best costume design.

After doing a bit with Jimmy Kimmel about the Oscars streaker at the 46th Oscars in 1974, John Cena presented the award to "Poor Things" costume designer Holly Waddington.

"Thank you to the academy, thank you to my fellow nominees," Waddington began. "It's an amazing privilege to be in the same room as you all. You're the people who inspired me to be a costume designer in the first place."

"'Poor Things' was a very rare opportunity to be really free and artistic in a creative process as a costume designer," she continued. "Thank you, Yorgos [Lanthimos], for that and for making such bold and brave work."

Other nominees in the category included "Barbie," "Killers of the Flower Moon," "Napoleon," "Oppenheimer."

Christopher Nolan won the Oscar for best director for "Oppenheimer."

During his acceptance speech, Nolan thanked Universal Studios and the authors of the biography on which the movie is based, "American Prometheus," by Kai Bird and Martin J. Sherwin.

He also thanked all the cast members including Matt Damon, Robert Downey Jr., Emily Blunt, Florence Pugh and Cillian Murphy, as well as his wife, "the incredible Emma Thomas … producer of all our films, and all our children. I love you."

"Movies are just a little bit over 100 years old," he continued, adding, "We don't know where this incredible journey is going from here, but to know that you think that I'm a meaningful part of it, means the world to me. Thank you very much."

In addition to best director, Nolan was also nominated tonight for best adapted screenplay, which ultimately went to Cord Jefferson for "American Fiction."

This awards season, Nolan has won a Golden Globe for best director and BAFTAs for best director and best film.
