In the build-up to The Flash's release, there were persistent rumors that Batman and Robin star George Clooney was set to appear alongside fellow big-screen Batmen Michael Keaton and Ben Affleck in the Scarlet Speedster's first solo outing.
The reports were widely dismissed at first, but sure enough, Clooney showed up right at the end of the film. When Barry Allen exits the courthouse following his father's aquittal, he gets a call from someone he assumed to be his reality's version of Batman (Affleck), and is more than a little confused when Clooney steps from the limo.
Though some fans were happy to see Clooney back as the iconic DC Comics hero, the scene - like the movie itself - proved to be highly divisive, and it was generally felt that the actor was brought back for little more than a quick visual gag.
Had a sequel to The Flash been greenlit there's a chance we would have seen Clooney's take on the Caped Crusader again, but after a dismal box office performance and the advent of a new DCU, we'd say the chances of seeing him again are very slim.
And that seems to be more than okay with Clooney!
The actor has previously indicated that his appearance in The Flash was a "one and done," and while speaking to ET, he was much more blunt about potentially donning the cape and cowl again.
"There aren't enough drugs in the world."
"Directed by Andy Muschietti, The Flash features Barry Allen traveling back in time in order to change events of the past. But when his attempt to save his family inadvertently alters the future, Barry becomes trapped in a reality in which General Zod has returned, threatening annihilation, and there are no Super Heroes to help. That is, unless Barry can coax a very different Batman out of retirement and rescue an imprisoned Kryptonian…albeit not the one he’s looking for.
Ultimately, to save the world that he is in and return to the future that he knows, Barry’s only hope is to race for his life. But will making the ultimate sacrifice be enough to reset the universe?"
The Flash is produced by Barbara Muschietti and Michael Disco, with a screenplay by Christina Hodson, and a screen story by John Francis Daley & Jonathan Goldstein and Joby Harold, based on characters from DC. Warner Bros. Pictures presents a Double Dream/a Disco Factory production of an Andy Muschietti film.
