I don’t see why Disney would even have it listed on their slate (even cryptically like that). Fox owns the original movie in perpetuity. I think Disney would want to focus on stuff that’s 100% theirs.
Fox owns the distribution rights, not the film. I have no idea how big of a slice that cuts from Disney. But if it’s something that cannot be changed, and profits can be generated from the property despite the distribution rights, I do not see why they would not pursue that. Obviously, the films with expiring distribution rights make more sense to wait on.
