Fox may be trying to court an A-list star for X-Men: Dark Phoenix with them reportedly wanting Angelina Jolie to join the followup to X-Men: Apocalypse.
However, if we operate under the mindset that Jolie is being courted for a role in X-Men: Dark Phoenix, it does not state who this role could be for.
Even if Fox is ultimately not able to bring Jolie aboard, this possibly being the role they have in mind further confirms them drawing from the Dark Phoenix Saga storyline.
Throughout the seventeen year history of the X-Men film franchise, the producers and studio secured their fair share of big names.
