'Suicide Squad' release date rumors: The Flash to make a cameo?

Some fans have been analyzing the trailers that have been released for the upcoming "Suicide Squad," and they have come to the conclusion that Ezra Miller's Flash will make a cameo in the movie.
ComicBookMovie.com reports that some fans were able to deduce that the Flash will make his appearance during the origin story of Captain Boomerang (Jai Courtney). In the "Justice League" trailer, Miller's Flash emits bolts of electricity whenever he enters the Speed Force. In one of the released "Suicide Squad" clips, there's a sequence of Captain Boomerang in front of what looks like a bank vault door, and the same electricity seems to be emanating from in front of him. It looks like Captain Boomerang will attempt to rob a bank and the Flash swoops in and stops him.

To those unfamiliar with the lore, Captain Boomerang is actually one of the Flash's main adversaries. The Boomerang in the "Suicide Squad" movie is the original one, and it is an alias used by George "Digger" Harkness. The Boomerang was enemy to both Flashes, Barry Allen and Wally West.
With "Suicide Squad" showcasing appearances from mostly Batman villains (Harley Quinn, Killer Croc, Deadshot, The Joker), it only seems right that Captain Boomerang's main adversary makes an appearance as well, even if it's just for a small cameo.
This would mean a big treat for the fans, since they were expecting to see their first glimpse of The Flash in action in next year's "Justice League." If he pops up in "Suicide Suicide," that would've saved the fans a lot of time to speculate on what the Flash's heroics would look like.
"Suicide Squad" is only more than a week away, and fans could not be more excited, as the movie looks to be a lot more colorful than DC's "Batman v Superman: Dawn of Justice."
"Suicide Squad" comes out Aug. 5.
