Massive Spoiler Warning!!
During the film, DC Fans are treated to tons of cool Easter Eggs filled back stories through flashbacks. These flashbacks were some of the coolest scenes in the film and one that really stood out in particular (not because it was well filmed), was a scene that featured the scene stealing Jai Courtney's Captain Boomerang in the process of a big diamond heist. During the heist Boomerang trips the alarm and who is there to capture him? None other than Ezra Miller's The Flash making a kind of cool cameo? I was personally was not impressed with Znyder's scene and thought it felt kind of awkward.
David Ayer also confirms that the scene was always intended to be in the film, but was shot post production in London where Ezra Miller was filming his scenes as The Flash for Zack Snyder's Justice League.
“Flash was always in the movie, we just got lucky because Justice League was happening and they had the uniform, they had the assets, so we were able to get that photography.”
