Director Ryan Coogler had been preparing the sequel for almost a year when Chadwick Boseman died, causing him to take a new direction focused on T'Challa's sister, Shuri, played by Letitia Wright
"Black Panther" returns to cinemas worldwide this week, having lost its star with the tragic early death of Chadwick Boseman, but none of its determination to push for greater diversity in superhero movies.
Boseman, who died from cancer two years ago aged 43, makes several flashback appearances in "Black Panther: Wakanda Forever".
The real-life grief of the filmmakers is reflected in the film as Wakanda struggles to survive following the death of Boseman's character, King T'Challa.
