On Monday, Downey Jr. shared a picture of himself posing with his statuette, but the best part of it all had to be him matching it.

Downey Jr. — who was last nominated in 2009 forTropic Thunder— was in a stacked group of nominees at the 2024 Oscars, but he ultimately beat outAmerican Fiction’sSterling K. Brown,Killers of the Flower Moon’sRobert De Niro,Barbie’sRyan GoslingandPoor Things’Mark Ruffalo.

The minute he took the stage to accept his award, Downey Jr. started off his speech with lighthearted jests. “I’d like to thank my terrible childhood and the Academy, in that order,” he began.

He then cracked a joke at his partner, saying, “I’d like to thank my veterinarian — I meant wife —Susan Downeyover there. She found me, a snarling rescue pet, and loved me back to life. That’s why I am here. Thank you.”

Later, he thanked director Nolan, who’s also the writer and producer ofOppenheimer, as well as producerEmma Thomasand his costars.

“Here’s my little secret: I needed this job more than it needed me. Chris knew it, Emma made sure she wrapped — surrounded me with one of the greatest cast and crews of all time,” he said. “Emily [Blunt],Cillian [Murphy],Matt [Damon]… it was fantastic and I stand here before you a better man because of it. You know, what we do is meaningful, and the stuff that we decide to make is important.”
