During this year's San Diego Comic-Con. Warner Bros. revealed that the upcoming solo movie starring Ezra Miller's Flash had been retitled Flashpoint. This, of course, indicates that it will be based on the 2011 DC Comics event of the same name, in which the DC Universe was fundamentally changed -- changes that included Thomas Wayne, not Bruce, becoming Batman.

Details on Warner Bros.' Flashpoint film have been scarce, but that hasn't stopped fans from hoping to see certain aspects of the comic's alternate DC Universe come into play. But if Thomas Wayne will be in the film, actor Jeffrey Dean Morgan -- who played Thomas in last year’s Batman v Superman: Dawn of Justice -- is keeping quiet about his involvement.

In a recent appearance on Jimmy Kimmel Live, Morgan was asked if he’ll be in the film, at which point Morgan clammed up. Later on, he said that he knew nothing about the film, but for fans hoping to see him don the caped crusader's cowl, his previous reaction appeared to speak volumes.

In DC Comics' Flashpoint event, Barry Allen accidentally rebooted the entire universe, leading to drastic changes in continuity. One of the biggest resulted in Thomas Wayne taking on the mantle of Batman. Thanks to Barry’s meddling, young Bruce Wayne was the one shot that fateful night in Gotham city's Crime Alley. In their grief, Thomas and Martha (played in BvS by Morgan's Walking Dead co-star Lauren Cohan) took two wildly different paths, with Thomas becoming a kill-happy Dark Knight, and Martha transforming into the Joker.

Flashpoint stars Ezra Miller as Barry Allen, Kiersey Clemons as Iris West, Billy Crudup as Henry Allen, Ray Fisher as Cyborg and possibly Gal Gadot as Wonder Woman. Originally intended to hit theaters on March 16, 2018, when it was titled simply The Flash, the film currenly has no release date.
