Of course, if Grant Gustin’s Barry Allen from the Arrowverse series runs into Ezra Miller’s take on the character in The Flash movie, it wouldn’t be the first time the alternate Flashes have met.
As we now know, The Flash movie will include at least two iterations of Batman, but might we also see multiple other versions of Barry Allen?
If getting Grant Gustin into The Flash movie ultimately doesn’t work out, Wallace says that there will still always remain an open invitation for Miller to come back to the Arrowverse.
Meanwhile, The CW’s version of The Flash is set to premiere its seventh season in January 2021.
