Now, while many fans of The CW's The Flash weren't especially pleased to hear that an entirely different actor would be playing Barry 'The Flash' Allen in the DCEU, the sheer charisma of the newly arrived Ezra Miller seems to have won over the vast majority of doubters. In fact, between stealing half of the scenes in the recent Justice League trailer, and putting in an excellent surprise cameo appearance somewhere else recently, Miller has already very much shown himself to be not just a capable Barry Allen, but a worthy wielder of the Speed Force, too.
What's more, Miller has also already demonstrated a fondness for geeking out in interviews - something that has a tendency to lead to questions like this one:
Is Ezra Miller Not-So-Subtly Teasing A DCEU/CW Crossover?
Yup, that's right. A crossover between the DCEU (with Miller as The Flash) and The CW (with Grant Gustin as the Scarlet Speedster). Was just heavily teased by the man who plays The Flash in the DCEU. And you aren't dreaming.
The only problem? It's entirely possible that Miller was just goofing around. His comments, y'see - from a recent interview with MTV - are... well, have a read of them for yourself:
"[Grant Gustin is] a boss. I can’t wait to see him, eye to eye, adrift in the Speed Force — our eyes will lock and, in that moment, we will both know the truth. What truth? I dare not say."
Now, on the surface, that sure seems to be a confirmation that Miller fully expects to run into Gustin on screen one day - which would be absolutely huge news. The big problem of course being that upon closer inspection, Miller's comments also very much come across as a joke.

Here's the thing, though:
What If Ezra Miller ISN'T Joking?
After all, DC Comics history has already established a whole lot of precedent for reality hopping adventures, and for heroes being able to meet alternate versions of themselves. DC Comics has traditionally always maintained not one universe, but a 'multiverse' - an infinite array of alternate worlds and realities, some vastly different from the one we're used to, and others only fractionally changed.
What's more, The Flash has often been the hero chosen to explore the possibilities that lie therein. Heck, in recent months, one classic iteration of The Flash even managed to break down the barriers of the current 'New 52' reality in the DC Comics universe, which largely eliminated the multiverse, and find his way to the modern comic-book universe.
In the context of that underlying premise then - that there can be multiple universes, featuring dramatically different versions of the same character - there's really nothing stopping the DCEU from exploring some sort of crossover other than a potential unwillingness to confuse audiences.
The CW's Take On The Flash Might Have Already Opened The Door To A Crossover
Y'see, The Flash has long played with the concept of a multiverse - and has indeed already introduced an alternate reality version of Grant Gustin's Barry Allen (above), as well as the concept of their being multiple (non-Allen) versions of The Flash himself.
What's more, the show has also already gently teased a future 'crisis'...
...seeming to suggest that the ultimate goal of the show is to adapt the legendary Crisis on Infinite Earths crossover event - an iconic DC story-line from the mid 1980's that featured - you guessed it - multiple versions of some of our favorite superheroes.
Now, there's no guarantee that The Flash will actually bring a version of the Crisis to The CW - for one thing, it'll have to stay on the air until 2024, according to that newspaper headline - but whatever happens, it's opened up a window of possibility. Were the DCEU to decide to adapt Crisis on Infinite Earths, after all, it could well find itself in need of recognizable alternate versions of its leading heroes to appear as part of it. While the likes of Batman and Superman would already be well covered by previous movies (anyone else like the sounds of a Christian Bale/Brandon Routh cameo double whammy?), The Flash has far less cinematic experience.
Which could well open the door for an appearance by a certain Grant Gustin, whose television appearances - whether The Flash is still on the air or not at that point - have already established the in-universe possibility of such a crossover. In other words?
If The DCEU Did Decide To Feature A Crossover, The CW's Flash Is Already Ready To Roll
As, from the sounds of his recent comments - lighthearted though they may have been - is the DCEU's Ezra Miller.
Which means that we can sleep easy tonight, safe in the knowledge that while an epic Flash crossover isn't currently on the cards, it could still happen. And hope is sometimes all we need.
Well, hope, and a whole lot of gloriously nerdy Flash-themed Easter eggs...
What do you reckon, though?
Would you actually like to see Ezra Miller and Grant Gustin's two Flash's cross over on the big screen?
