The Flash is all set to speed into theaters on June 2023. However, according to a new report from an industry insider from Geeks Worldwide, some last-minute changes have been made in the direction of the current DC Studios co-CEO, James Gunn.The upcoming film will not only serve as the reset button for the DC Film Universe by changing the cinematic continuity of the Snyderverse to James Gunn's DCU but will also feature the highly anticipated returns of Michael Keaton's Batman and Michael Shannon's General Zod, following their explosive reveals in the trailer released in February. Both were last seen in Batman Returns and Man of Steel, respectively.As per director Andy Muschietti, the original plan for The Flash's conclusion was to set up a newly formed Justice League team, where Keaton would replace Ben Affleck's Batman and Sasha Calle's Supergirl would fill the Kryptonian role in place of Henry Cavill's Superman. However, this is now reportedly not the case as Gunn seeks to establish his newly acquired DC Universe in his own way.The Flash ending is now more "vague," but is cameo heavyKC Walsh@TheComixKidOn #TheFlash yes, there is some bad info going around due to some misunderstanding because of the vagueness of how it ends, I will correct what I can without revealing spoilers51838On #TheFlash yes, there is some bad info going around due to some misunderstanding because of the vagueness of how it ends, I will correct what I can without revealing spoilers https://t.co/aC3FalzLriAs per Geeks Worldwide's KC Walsh, The Flash has now undergone major changes, particularly the ending. This tidbit of news comes from one of the upcoming blockbuster's latest test screenings, which Walsh attended.Walsh stated that the film is now "complete," which makes sense, given that its premiere at CinemaCon is on April 25, which is only a week away from now. The eagerly awaited second trailer is also scheduled to go up online on this day.The insider added that the ending had been altered to be more "vague" and that the cameo that audiences had anticipated ultimately turned out to be different from what they had anticipated. The cameo in question is supposedly George Clooney's Batman from the critically panned Batman and Robin, as an earlier report from The Weekly Planet in February claimed that the actor would make an appearance in the film.KC Walsh@TheComixKidPeople saying/thinking a certain actor is definitely featured at the end of #TheFlash and it definitely means X are purposely misleading or lying to you. The ending is more vague than ever before and does not definitively say anything about where he is24027People saying/thinking a certain actor is definitely featured at the end of #TheFlash and it definitely means X are purposely misleading or lying to you. The ending is more vague than ever before and does not definitively say anything about where he is https://t.co/r4TPPR4NTGAccording to Walsh, The Flash contains several cameos besides Clooney's supposed one. The insider promised that the Speed Force in the film would feature a lot of cameos from multiple DC characters. He, however, specifically pointed out a "CW connection" and "a dream cameo," which, according to him, will be the "most talked about" cameo following the release of the film.The "CW connection" possibly refers to Grant Gustin's version of Flash from the eponymous CW series of the same name. However, Gustin has denied his appearance in the film, thus implying that the ending could only show footage of him from his world.BLURAYANGEL 🦇@blurayangelOver or under 50% chance Christian Bale’s Batman makes an appearance in The Flash movie?263675Over or under 50% chance Christian Bale’s Batman makes an appearance in The Flash movie? https://t.co/FPa5wNFZ7tThe "dream cameo" report, however, remains to be seen. But given that the insider said it would be the "most talked about" cameo, it could possibly refer to Christian Bale's Batman, as fans have universally praised his take on the Dark Knight, with the film possibly showing footage of him from his universe.Walsh added that the ending of The Flash had undergone a fairly controversial change. There are no longer references to Zack Snyder's Justice League. Walsh earlier supported and corroborated a rumor from another industry insider, MyTimeToShineHello, who suggested from her scoop that this would be the case.This is not very surprising, as YouTuber Grace Randolph had earlier revealed that The Flash had removed all teases related to the Snyderverse from its end in the direction of James Gunn. Randolph said that the ending had completely cut off Henry Cavill's Superman, Gal Gadot's Wonder Woman, Sasha Calle's Supergirl, and Michael Keaton's Batman. However, Calle and Keaton will be present in the film for a major portion of its runtime.The Flash plot and cast detailsThe Flash@theFlashOn June 16, worlds collide.
