On the one-year anniversary of his unexpected death, celebrities including Lupita Nyong'o, Viola Davis and many others honored the memory of the "Black Panther" star.

Nyong'o and Michael B. Jordan, who starred alongside him in the Marvel Cinematic Universe, offered up heartfelt memories of the late actor.

"I did not know that I could miss both his laughter and his silence in equal measure. I do. I do... One year after his passing, the memory of @chadwickboseman remains this alive in me," Nyong'o wrote, sharing a photo of them sharing a hearty laugh.

Jordan shared a picture of himself with his former co-star at a formal event, captioning it: "Not a day goes by bro… Love and miss you but I know you still with us."

Marvel Studios also commemorated Boseman's legacy, writing, "Honoring our friend, our inspiration and our King, Chadwick Boseman."

Many others paid tribute to Boseman, with Josh Gad re-sharing one of the last text messages he received from him.

"Not a day goes by one year later, where it doesn’t still hurt. But in the darkness, he always reminds us of the light. He was an angel on this planet and is now a Saint on high. Love you and miss you more than ever… forever," he wrote.

Kerry Washington also honored Boseman, writing, "One year without Chadwick Boseman. Thank you for watching over us. We miss you King."
