The DC Multiverse may be introducing a third Barry Allen if new set photos from The Flash feature film are to be believed.A set of four photos from The Flash were shared on Twitter, which shows Ezra Miller's Barry Allen talking to someone who is wearing an almost identical civilian outfit. Both Miller and the other individual have on a t-shirt, multi-colored jacket and jeans. They're both walking down a sidewalk holding a conversation, with the duo making exaggerated gestures with their hands as the camera crew follows close behind.RELATED: The Flash Movie Is Adapting Superman's Flashpoint Story - Without Superman

As many of the commenters have pointed out in the Twitter thread, the unknown actor appears to have a piece of visual effects equipment strapped to his back. The working theory is it's a rig to replace the actor's face with Ezra Miller's in post-production, meaning when The Flash opens in the fall of 2022, audiences will see Miller holding a conversation with his double from the multiverse.

Previous set photos from the upcoming Warner Bros. film gave fans a look at Michael Keaton's Bruce Wayne, Sasha Calle's Supergirl and a possible Batmobile. It was the first time fans got a glimpse of Calle in the Supergirl suit, after director Andy Muschietti shared a close-up image of Supergirl's Kryptonian costume for The Flash.

Ezra Miller and Grant Gustin's versions of The Flash famously met each other in The CW's event series "Crisis on Infinite Earths." It was the sixth time the network's Arrowverse series crossed over with each other, and saw the death and rebirth of the multiverse. One of the episodes featured Gustin's Barry Allen travel into the Speed Force, where he met Miller's Scarlet Speedster. It was a major moment for fans of the Arrowverse and DC Extended Universe since the two franchises had never interacted before. Of course, there are also rumors that Grant Gustin will pay back Miller's cameo by making an appearance in The Flash. Other major surprises and cameos from "Crisis on Infinite Earths" included Constantine, Lucifer and Spectre, along with glances at the Earths from Stargirl and Titans.

The Flash set photos aren't the only thing leaking from the highly-anticipated film. A leaked promo suggested another unannounced hero would be joining The Flash, after concept art showed someone with a spoiler tag over their face sitting next to Barry Allen in the Batmobile. The video was quickly removed from Twitter, but it was available long enough to kickstart the speculation train.

Ezra Miller's Barry Allen, Michael Keaton and Ben Affleck's Batman and Sasha Calle's Supergirl will star in The Flash, racing to theaters on Nov. 4, 2022.
