They would do that if Larson doesn't want it, not because of the box office. You people are also forgetting there's a muslim character as co-lead in this movie.
I still can't believe how they thought changing the title from Captain Marvel 2 to The Marvels was a good idea.
They had a 900M+ movie on their hands if they had made CM 2 into Captain Marvel: Secret Invasion, but no, they wasted the storyline by making a shitty show and wasting CM's sequel to link it into a show that nobody watched (Ms Marvel). 💀
