Back when Batman v. Superman: Dawn of Justice was first released, eagle-eyed viewers noticed that Zack Snyder had cast fellow Watchmen contributor Jeffrey Dean Morgan in a cameo capacity. Morgan appeared briefly in the opening flashback scene of the film, where he played Bruce Wayne's father Thomas Wayne. While this at first appeared as nothing more than a fun nod, the casting would take on a whole new meaning when The Flash (Ezra Miller) would introduce elements of time-travel in the DC Extended Universe film.
At the time, it was strongly hinted that a Flash solo film would borrow from the 2011 comic event Flashpoint, which featured Barry Allen creating an alternate timeline after going back to the past to save his mother. This act altered the entire history of the DC Universe. Case in point, Bruce Wayne was the one who died in that alley, and it was his father Thomas Wayne who put on a cape and cowl to fight Gotham's criminals as a much more violent Batman.
Therefore, it was widely assumed that Morgan had been cast in the role of Thomas Wayne so that the actor could one day play Flashpoint Batman in a Flash-centric movie. However, what was almost a certainty at one point is now cast in doubt.
During this past weekend at Comic-Con International in San Diego, Jeffrey Dean Morgan was asked in an interview with MTV the status of his role as Thomas Wayne. "When Zack Snyder was involved in the DC world more, I think that there was a real possibility," The Walking Dead actor said. "But now that he's kind of stepped away a little bit... I've heard different things, that Flashpoint might not be going in that direction, it will be more of an origin story for Flash."
As Morgan says, current reports have stated that the Flash solo movie may go in a different direction. But that doesn't mean Morgan has given up on the role. If anything, it sounds like he would really like to take a crack at Flashpoint Batman. "I'm always here, I would love to do it," the actor added.
"I'll keep talking about it just because it's really fun to talk about, and I really would like Warner Bros. to open their ears a little bit."
Hopefully, the studio really is listening.
The Flash solo film 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 is currently expected sometime in 2020.
