Chadwick Boseman, who played T’Challa in Marvel’s “Black Panther,” died of colon cancer on Aug. 28. He was 43.

According to a statement from his family, Boseman had been fighting cancer for four years, during the filming of “Black Panther,” “Marshall,” and his most recent project, “Da 5 Bloods.”

“Chadwick was diagnosed with stage III colon cancer in 2016, and battled with it these last four years as it progressed to stage IV,” the statement said. “A true fighter, Chadwick persevered through it all, and brought you many of the films you have come to love so much.”

Boseman also portrayed baseball legend Jackie Robinson in 2013’s “42,” and James Brown in “Get on Up” in 2014. In 2018, Boseman appeared on Variety‘s Actors on Actors series with Viggo Mortensen, during which he discussed the impact of “Black Panther.”

“‘Black Panther’ is a culmination, and it definitely is a change. I feel now that people are like, ‘Oh. Wait, wait. I thought, some people thought that might’ve just been a fluke or a trend, whereas I think what people are realizing now is, ‘Oh, wow. There is a wealth and there’s a market of stories here,'” Boseman said. “And when you leave out a great part of what has made this nation, you know, all of the contributions, you’re also leaving out a lot of great stories. There are a lot of really, really cool things that could be learned and loved by an audience. And people are starting to realize like, ‘Oh man, I didn’t even know that existed.'”
