Kinberg is a fan of the character and cast Halston Sage as the pop-singing mutant.

So, Dazzler, as a favorite character of mine and yours, was on that list.

Genosha was on that list.

Then some things that we didnt get to do, like the Danger Room, a proper Danger Room.

The song Dazzler sings is also an original tune penned for the movie by the band Odessa.

Are we supposed to believe Jean (Sophie Turner) is dead at the end?No.

so that defeat Vuk (Jessica Chastain), Jean seems to kill herself.

But the final shot is of a Phoenix-esque shape in the sky.

Beyond the corporal, beyond human, beyond mutant into something else.

That, for me, felt in many ways true to the essence of the comic.

Did they really reshoot the end ofDark Phoenixbecause it was too similar to another Marvel film?Not exactly.

The massive train battle that climaxesPhoenixwas something that was added during additional shooting forPhoenix.

And the franchise itself has been about family and, strangers come together to form a family.

My original ending didnt have the family coming back together as one.

I loved the ending ofCaptain America: Civil War.

So initially my big action set piece was gonna be New York City.
