These are uncharted waters. The Marvel Cinematic Universe has become a mega-franchise that produces hits so dependably that it’s acquired a logic of its own, which does not resemble normal human artistic endeavor.
In 2018, Marvel Studios produced Black Panther, a profoundly successful movie about a character who was not particularly well-known before he started showing up in Marvel movies. The film made a staggering amount of money, with a $700 million domestic box office take. It was the #1 movie of the year in the United States, even beating that year’s Avengers crossover.
They planned to make a sequel, of course, with Chadwick Boseman returning as King T’Challa. Writer-director Ryan Coogler started working on a script, and most of the original cast signed on for the second movie. They were about seven months away from the start of filming on Black Panther 2 when the news broke that Boseman had died of colon cancer, a condition that he’d been struggling with privately since 2016.
At that point, the normal thing for the studio to do would be to announce that the film was cancelled, and that the MCU would regretfully move on without Black Panther. Instead, they decided to make the movie anyway, rewriting the script to have the lead character die offscreen on page 2.
This is a bizarre way for a movie studio to behave. They made a two hour and forty-minute film about how bummed they are that they couldn’t make a sequel to Black Panther, and released it to theaters, and then everybody showed up and loved it anyway.
