It looks like the next X-Men feature film is getting closer and closer to being officially announced. While Fox has remained quiet about the future of their main X-Men franchise, a number of entertainment production websites have tracked an unannounced X-Men film's progress over the last few months. A new X-Men film, one that's not the previously announced "New Mutants" film or the sequel to "Deadpool," was first hinted at in January. The working title, "X-Men: Supernova," indicated that it might be based on the "Dark Phoenix Saga" storyline.

Now, the film's production listing on My Entertainment World has gone a step further: it now includes a synopsis -- one that, if official, confirms the film will be based on the classic X-Men storyline. The listing also states the film will starting shooting in June.

Gathered together by Professor Charles Xavier to protect a world that fears and hates them, the X-Men had fought many battles, been on adventures that spanned galaxies, grappled enemies of limitless might, but none of this could prepare them for the most shocking struggle they would ever face. One of their own members, Jean Grey, has gained power beyond all comprehension, and that power has corrupted her absolutely! Now they must decide if the life of the woman they cherish is worth the existence of the entire universe!

Of course, there's still a possibility that this synopsis is a fake out, as Fox has not confirmed the existence of a follow-up to 2016's "X-Men: Apocalypse" just yet. It's also worth pointing out that Production Weekly has "X-Men: Supernova" listed alongside the working titles "Dark Phoenix" and "Teen Spirit." There's also another X-Men project listed right after it, which has the alternate titles "Hellfire" or "Heaven." It's likely that that's the untitled "X-Men" TV series pilot that Bryan Singer has signed on to direct, since the X-Men TV series was previously titled "Hellfire" and there's a new listing for the project in My Entertainment World's TV section.

There are other rumors that seemingly corroborate that "X-Men: Supernova" will tackle "The Dark Phoenix Saga." All the teases dropped about the "Apocalypse" follow-up hint towards the X-Men going to outer space for a retelling of "The Dark Phoenix Saga." The storyline previously served as the inspiration for "X-Men: The Last Stand," which took a number of liberties with the tale.

The next film in the "X-Men" film franchise is "Logan," Hugh Jackman's final outing as Wolverine. That film opens on March 3. Additionally, "New Mutants" and "Deadpool 2" are slated to begin production soon, although neither has a release date yet. "Gambit" starring Channing Tatum has been in the works for a while, but has been plagued with director problems. The film has yet to find a new director following the departure of Doug Liman in August.
