Brie Larson knows that actions speak louder than words. 

Although clapping is a simple gesture, the act is considered a sign of approval and a "job well done" — which is why Larson's arms remained stiffly to her sides as the rest of the Dolby Theatre congratulated Casey Affleck on his Oscars win for best actor.

Larson's reaction did not go unnoticed. Affleck, who won for his role in "Manchester by the Sea," was accused of sexually harassing two women who worked on his film, "I'm Still Here," back in 2010. He has continually denied these allegations, and both cases were ultimately settled out of court for undisclosed amounts. 

But without saying a word, Larson showed the world that she isn't willing to turn a blind eye to Affleck's past. After handing off the award to Affleck, the actress maintained an icy glare and refused to clap.

And nearly two weeks later, she still has no regrets about her shameless snub. 

On Wednesday, Larson confirmed to Vanity Fair that her reaction was very intentional.

"I think that whatever it was that I did onstage kind of spoke for itself," Larson told the magazine at the premiere of "Kong: Skull Island." 

Normally, this type of "silent protest" would ignite a debate over Larson's professionalism — but in this situation, viewers understood.

In the 2015 drama "Room," Larson portrayed a sexual assault survivor. Her award-winning performance earned her the Oscar for best actress in 2016 — but her work for sexual abuse victims didn't end once filming came to a close. 

Larson has remained an advocate for sexual assault survivors. She recently told Jane Fonda in the latest issue of The Edit, "We can't take any steps backward in allowing people to think abuse is their fault. It's the people-pleaser disease." During Lady Gaga's performance of "Til It Happens To You" at last year's Oscars, Larson even made it a point to hug every rape survivor that joined Gaga on stage. 

Twitter applauded Larson for her lack of applause.

But Larson has made it clear that she has said all she wants to say on the matter.

“I’ve said all that I need to say about that topic," she concluded.

Because sometimes you can say a lot without saying a single word.
