The entertainment media is pretty sure that Fox will be filming a movie this Summer called X-Men: Supernova, which will adapt the Dark Phoenix Saga that was originally massacred in X-Men: The Last Stand, and which could possibly serve as the directorial debut of X-Men producer Simon Kinberg. Of course, Fox has never officially announced this movie, and in fact, when Kinberg himself was asked about the "announcement" he'd be directing the film in an interview recently, he pushed back, saying:
They didn't announce it, somebody broke a story about it that's premature, but we have been talking about what the next X-Men movie would be since post-production on the last X-Men movie. We are prepping the film, can't say much more than that, but we're excited to get back into telling the story of the mainland X-Men.
But it's too late, Kinberg. This is out of your hands now. You're making a new X-Men movie, it will be called Supernova, it's about the Dark Phoenix Saga, and you're directing the damn thing. We've put too much effort into reporting about this thing. This is the exact same way Justice League came about. DC wasn't even planning on making one, but years worth of rumors actually willed it into reality. For an example of this effect, just look at poor Nicholas Hoult, who, when asked about his role in the film, was pretty sure he's involved in it, even though Fox is supposedly still figuring things out.
I think I'm involved. I'd be happy to go back – I love playing that character and I love everyone involved and I know there's one in the works.
X-Men: Supernova, about the Dark Phoenix Saga, directed by Simon Kinberg, and starring Nicholas Hoult as Hank McCoy will begin filming this Summer. So it has been written, so it shall be. Trust us. We're never wrong about these things.
