Since November, rumors have been swirling around what the next X-Men film would be about. At the time, LRM Online reported that Fox was looking at doing a soft reboot of sorts for the franchise, similar to how X-Men: First Class reset things with a new time period and characters after the disappointing X-Men: The Last Stand.
Insiders close to the next film confirmed that it would move away from the themes of X-Men: Apocalypse and focus on a classic comic book storyline, with newcomers to the franchise like Sophie Turner (Jean Grey), Tye Sheridan (Cyclops), Alexandra Shipp (Storm), and Kodi Smit-McPhee all said to return and would be front-and-center in the new film.
Then, a few weeks ago, industry outlet Production Weekly revealed that Fox was prepping a film called X-Men: Supernova for production, which naturally led to speculation that it would an adaptation of the “Dark Phoenix” storyline. Now, an upcoming February 9th edition of the Production Weekly trade further supports this conclusion with an entry for the next X-Men film that reads as follows:
“X-Men: Supernova” (w/t “Dark Phoenix” / “Teen Spirit”)
So the working titles for X-Men: Supernova are “Dark Pheonix” and “Teen Spirit,” which confirm that the film will focus on the “Dark Phoenix” storyline, the second time the movie franchise has done so. The only confusing thing is the use of the “Teen Spirit” title, as producer Simon Kinberg has stated that the next film will be set in the 90s, which means that all of the previously-mentioned teen characters would be well into their 20s. Perhaps there will be an even younger group of mutants introduced in the film? It’s hard to say at this juncture, but at least we know that a (hopefully) proper adaptation of the “Dark Phoenix” saga is on the way.
