If Alita: Battle Angel gets its sequel, Robert Rodriguez and James Cameron already have their pitch process, and the world of Alita, down to a science.
Since the ball’s already in Disney’s court, they may want to consider using Dania Gurira’s position in the Marvel Studios family as a good incentive to casting her as the Crimson Wind in Alita: Fallen Angel.
Which, in practice, would be satisfying two wishes of the fandom, as that’d mean we’d be getting a sequel in the first place.
But it’s best to take these sorts of things one step at a time.
