Warner Bros. and DC Comics have already drawn a line in the sand, so to speak, regarding the separation of DC’s Extended Universe—the DCEU—and the universe found on TV.

That’s the reason why Stephen Amell and the Grant Gustin of DC-The CW’s "The Flash" and "Arrow" wouldn’t have a chance to reprise their roles in the movies.

However, there’s no love lost between the cast of these TV shows and the Flash of the DCEU. Of particular note is what John Wesley Shipp—currently the Flash of Earth-3 in the CW series and the former Barry Allen of the 90s—thinks of this conundrum.

Ezra Miller is excited

Ezra Miller, for his part, is enjoying working in the extended universe of Justice League, where he is playing the part of the Scarlet Speedster.

While co-star Ben Affleck thinks that the heroes in the film are coming together well—each having their own personalities and quirks, as well as their contributions in terms of powers and vehicles—Miller thinks that this DCEU Flash holds his own against the other heroes. He reiterates that, with all their differences, each one of them brings their own ‘brand of fun’ when they are shooting.

It will be exciting to see how that fun translates to the big screen.

Already, the crew looks complete—Batman, Superman, and Wonder Woman are accompanied by key people in their respective films (Alfred Pennyworth, Queen Hippolyta, Lois Lane comes to mind) as well as new counterparts in Aquaman, Cyborg, and The Flash.

How the Flash of Multiple Universes Come Together

Looking back to what John Wesley Shipp thinks about the Flashes of the DCEU so far, he was quoted in a tweet that there’s no problem, so to speak.

While the DC multiverse is still being explored in the TV series, it is in full swing in the comic books. This could be the reason behind Shipp’s comment saying that “the Speed Force is big enough” to the presence of three different Flashes from three different universes. Think of the movie universe as a different dimension from Barry Allen’s (Grant Gustin) and Earth-3 Flash (John Wesley Shipp).

It should be interesting to watch things pan out for the heroes in their respective universes.

Wherever he might be seen, Warner Bros. guarantees that they have big plans for the Scarlet Speedster. In the comic books, there’s already a title spanning event that happened during Flashpoint involving Barry Allen trying to rectify the mistakes of the past.

The CW’s "Flash" returns on October 10 for another run, while "Justice League" comes together on November 17.
