The Flash is one of the most highly anticipated DCEU projects for a number of reasons, the biggest being the multiversal plot that surrounds the Scarlet Speedster.
The Ezra Miller led project is being pieced together as one of the biggest multiversal projects attempted in comic book movie history. With Keaton and Affleck returning as their respective Batmen , it already has some of the biggest fan appeal a DC project can contain.
Add in the debut of Sasha Calle's Supergirl , and it's quickly becoming a dream project for any die-hard DC fan.
Now fans have more variants to wrap their heads around.
GRANT GUSTIN CAMEO IN THE FLASH
The Illuminerdi reported that Grant Gustin is set to make a cameo in the Ezra Miller-led The Flash movie as the Arrowverse's Flash.
EZRA MILLER AND GRANT GUSTIN BACK TOGETHER AGAIN
Ever since Ezra Miller made his way into the CW's Arrowverse with a cameo in the mega-crossover event Crisis On Infinite Earths, fans have been shouting from the rooftops for more crossovers with the cinematic and television adaptations of Barry Allen. And while Grant Gustin has made a name for himself in The Flash, this report of him making a crossover jump into the big screen is a huge moment for the actor, the character, and the fanbases.
The addition of Grant Gustin reprising his role as Barry Allen is the icing on the cake of a cake that is mostly icing. Even if this is just a one-scene nod like Miller's TV cameo in 2020, the arrival of the Arrowverse's leading man in the DCEU is a monumental moment for the TV's universe's large fan base that has been building since 2012.
Moving on from the Snyder era, Warner Bros. is pivoting the DCEU into a direction that allows for multiple versions of multiple characters to appear on big and small screens simultaneously. The Flash is rumored to be adopting the Flashpoint comic run that provides the perfect vehicle for such a concept.
One of the biggest critiques of the DCEU so far is its world-building strategy. Bringing in arguably the biggest character from the Arrowverse, which is praised for it's world-building, is a step in the right direction to get fans on board.
