US actor Chadwick Boseman, best known for playing Black Panther in the hit Marvel superhero franchise, has died of cancer.
The 43 year old died at home in Los Angeles with his family by his side.
Boseman had not spoken publicly about his diagnosis.
Boseman first came to prominence playing real-life figures – baseball great Jackie Robinson in 2013’s 42, and musician James Brown in 2014’s Get on Up.
However, it will be as the titular Black Panther in the blockbuster 2018 film he will be best remembered.
Boseman stars as the ruler of Wakanda, a fictional African nation with the most advanced technology on earth.
As well as winning critical praise and taking more than $1.3 billion US dollars (£973m) at cinemas worldwide, the film was widely seen as a cultural milestone for having a largely black cast and a black director, Ryan Coogler.
Boseman said last year that the film had changed what it means to be “young, gifted and black”.
Black Panther was the first superhero film to get a nomination for best picture at the Oscars.
He also played the same role in other Marvel films Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame.
The announcement will come as a shock to many as Boseman never discussed his 2016 diagnosis publicly.
However, fans started raising concerns over his health this year due to noticeable weight loss.
