On the one-year anniversary of Chadwick Boseman’s death, several of his friends, collaborators and admirers took to social media to honor him and his work. 

Boseman, famous for playing the titular role in Marvel’s “Black Panther” among many other films, died of colon cancer at age 43 on Aug. 28, 2020. His passing came as a shock to almost everyone — he had been diagnosed in 2016, but kept his illness private and continued to work.

Only his family and a small group of others were aware as he underwent surgeries and chemotherapy; despite the physically demanding nature of many of his last roles, even Ryan Coogler (director of “Black Panther”) and Spike Lee (director of “Da 5 Bloods”) have said publicly that they were completely surprised by the news.

Lupita Nyong’o, who played Nakia opposite Boseman in “Black Panther,” reflected on Boseman’s silent presence as well as his laughter, sharing a photo of the two of them on Twitter.

“I did not know that I could miss both his laughter and his silence in equal measure,” Nyong’o wrote. “I do. I do… One year after his passing, the memory of @chadwickboseman remains this alive in me.”

Jane Lynch added to Nyong’o’s post, saying that Boseman’s sudden death still “boggles the mind.”

Josh Gad re-shared his tweet from the day of Boseman’s death last year, which included screenshots of text messages Boseman had sent Gad. “Not a day goes by one year later, where it doesn’t still hurt,” Gad wrote. “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 and miss you more than ever… forever.”

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. #ChadwickBoseman https://t.co/uHOa8jLEKq
