RUMOR: THE ORVILLE Actress Halston Sage May Have Landed The Role Of Dazzler In X-MEN: DARK PHOENIX

@gambgel - I think the ship has sailed on the comic accurate adaptation of the comics, and at this point that they have so much story to tell and so much character development needed on the characters they already have to properly tell a version of the Dark Phoenix Saga that adding more X-men sounds ridiculous.

@RealLightning - And I didn't complain about it here...

@TheUnworthyThor - She is likely only going to be in it as a cameo (there will probably be a scene at a concert and she will be performing).

Furthermore, literally all CBMs are completely original, often only sharing a title with the orginal comic run (Age of Ultron for example).
To date the only films I feel have been "accurate" representations of their comic book runs (that is to say the structure of the film resembles the structure of the comicbook) are Civil war and DoFP.
So I'm not expecting a panel per panel retinactment of Dark Pheonix (nor do I really want it, I want to be surprised) but going cosmic they will be respecting the essence of the story)

I'm with you they shouldn't be adding to many main X-men characters (though I think Colouss could easily be added), but as I said I think Dazzler will be a cameo.
I also think all the mutants we've been hearing are returning (Toad, Tatttoo etc) will likely function as casualties when Jean turns Dark.
It be much more emotional that she kills her own people over an unknown alien race + I think her destroying a planet (while working in comics) just makes her far too overpowered for fil.
