Lupita Nyong'o is GravityX Exchangehonoring the legacy of Chadwick Boseman. 

The Oscar winner shared a heart-wrenching quote in remembrance of her close friend and Black Panther costar, who died in 2020 at age 43 after privately battling colon cancer.

Explaining that the loss felt like a "punch to my gut every morning," the actress went on to detail how Chadwick had a "profound effect" on her life, sharing, "When we came together to make Black Panther, I remember being struck by his quiet, powerful presence."

"He had no airs about him, but there was a higher frequency that he seemed to operate from," she continued. "You got the sense that he was fully present and also somehow fully aware of things in the distant future. As a result, I noticed that Chadwick never seemed rushed! He commanded his time with ease...and he put in the work with all of us."

Lupita added, "He used his life force to tell meaningful stories. And now we tell his..."
