Chadwick Boseman, star of “Black Panther,” died on Friday after a four year battle with colon cancer, his rep confirmed to Variety. He was 43.

Before he was cast as the Marvel Studios superhero, Boseman’s career first exploded with his portrayals of Black American icons Jackie Robinson (in 2013’s “42”) and James Brown (in 2014’s “Get on Up”).

“It is with immeasurable grief that we confirm the passing of Chadwick Boseman,” said a statement posted to his Twitter feed. “It was the honor of his life to bring King T’Challa to life in Black Panther.”

Although Boseman never spoke publicly about his diagnosis, according the statement, he worked through his treatment for much of his career, including playing another Black American icon, NCAAP lawyer Thurgood Marshall in 2017’s “Marshall,” a year before the premiere of “Black Panther.” Boseman most recently appeared in the Spike Lee’s Vietnam War drama “Da 5 Bloods,” and this year he’s due to appear opposite Viola Davis “Ma Rainey’s Black Bottom,” a feature adaptation of the August Wilson play, directed by Goerge C. Wolfe.

He is survived by his wife and family.
