To be clear, the casting has not been confirmed by Bryan Singer or anyone else connected to the project. It also didn't explicit quote the actress, because it was a report teasing an interview scheduled to be posted next week. However, the report was assured in its belief. It said:
Earlier today I spoke with Halle Berry for an interview that will appear on S & A next week. But to give you a tease, the first thing I did ask her was whether she would be returning as Storm in the next X Men movie, X-Men: Days of Future Past ... Well, she did confirm to me that she would be returning in the role. Most likely. Practically 90% sure. And she nodded a lot too.That's hardly a 100 percent guarantee, but a look at the storyline of "X-Men: Days of Future Past" adds yet some further confirmation.
The film's title points to it being based on the classic X-Men storyline, "Days of Future Past." The casting, including both original "X-Men" characters Patrick Stewart and Ian McKellen also points to that, as well, as it is a time travel tale, perfectly balanced to include both old and new characters and actors. Others already confirmed are Rogue (Anna Paquin), Shadowcat (Ellen Page) and Iceman (Shawn Ashmore).
Those who recall that storyline will remember it spanned "The Uncanny X-Men" issues 141 and 142, published in 1981. Written by Chris Claremont, it was drawn by John Byrne and inked by Terry Austin.
In the story, we see an alternate future which has been triggered by the assassination of Senator Robert Kelly by The Brotherhood of Evil Mutants. An older Kitty Pryde transfers her mind into a younger, present-day Kitty Pryde in hopes of preventing the event, which led to members of mutantkind being either killed or imprisoned in internment camps.
In the comics, that included those who were not X-Men, but were mutants, such as Franklin Richards, the son of Reed and Sue Richards of the Fantastic Four.
Only a few X-Men remain alive as the story opens: Kitty Pride, Wolverine, Storm (there's a hint that Halle Berry should appear), and Colossus. In the alternate future, all are killed, even Wolverine, despite his adamantium skeleton and rapid healing factor. He is vaporized by a Sentinel, too fast even for his healing process, with only the metal skeleton left behind.
However, Kitty Pryde's mission succeeds, and that dystopian future is gone, never to occur.
Rachel Summers, who took the name Phoenix, also traveled back in time as part of the story. Despite being from an alternate future, she stayed, and became a member of the X-Men.
The sequel is scheduled for a release on July 18, 2014.
