Spoilers for The Flash, but locking down its actual ending took quite a bit of effort.
The newly released Flash movie has been in development for…quite a long time, having survived several regime changes that hit the DCEU and Warner Bros. overall. It was decided around 2017 that the film would effectively function as a swan song for the DCEU movies, so its general endpoint was always going to be as a refresh for whoever ended up taking control of the films down the line. But even the final film as it’s currently in theaters had a few different permutations to its ending, up to and including one of its final big cameos.
Spoilers for The Flash from this point onward.
After saving the multiverse from the mess he created, Barry Allen shows up at a courthouse for his father’s hearing and meets up with Bruce Wayne. But instead of Ben Affleck, the Bruce he meets is actually George Clooney, who previously played the character back in 1997’s Batman & Robin. According to the Hollywood Reporter, this ending wasn’t the only version shot—in fact, it’s the third version of the movie’s conclusion, and one that only took shape back in January.
