Life moves pretty fast but not as fast as The Flash, the latest superhero from DC.

In the wake of James Gunn’s DCU shake-up, complete with a new slate and a confusing connection, the uneven DCEU still has three holdovers from the franchise formerly known as the Snyder-verse to hit cinemas.

So even as we try to wrap our head’s around what The Flash means for resetting the DC movie continuity we bring you the need to know info of the biggest, most important movie in the Justice League series.

The Flash release date

The Flash comes speeding into cinemas from 14 June, 2023 (16 June in North America) having been moved up a week from its 23 June release date.

The change, we assume, is to avoid competing too heavily with James Mangold’s Indiana Jones and the Dial of Destiny which comes out on 30 June.

It’s been a long road coming having lost a succession of directors including Dope filmmaker Rick Fukuyama, but now comes at us via It and Mama director Andy Muschietti.

The official runtime has been given as 2 hours 30 minutes, a mammoth runtime but given the plot is about time bending and offering the return of some previous franchise baddies and new threats that’s to be expected.

The Flash cast

Despite high profile personal issues this is a film centred on not one, but two Ezra Millers. Their personal life problems and legal issues have caused the film to be pushed back which has caused ripples since its the cornerstone of the DCEU and whatever comes next.

Reprising their role from Batman v Superman: Dawn of Justice, Suicide Squad and both versions of Justice League, Miller plays Barry Allen aka The Flash, a superhero who can tap into the speed force and travel through time.

Also returning from the wider DCEU is Kiersey Clemons as love interest Iris West, previously seen in Zack Snyder’s Justice League, Ben Affleck will cameo as the mainline Bruce Wayne/Batman in what might be his final time in the role.

Reprising their roles from Man of Steel are Michael Shannon as General Zod and Antje Traue as Faora-Ul, Zod’s second-in-command when Barry becomes trapped in a reality in which General Zod has returned.

Also Temuera Morrison reprises his role as Thomas Curry, Aquaman’s father.

Ron Livingston replaced Billy Crudup in the role of Barry’s incarcerated dad Henry, the film will dive into the mystery of Barry’s mother Nora’s death. Maribel Verdú (Pan’s Labyrinth) will play Barry’s late mother and form the emotional core of the film.

The two biggest casting coups are Sasha Calle as Supergirl, bringing the character to the big screen for the first time since Helen Slater’s much maligned 80s outing.

Michael Keaton is also back in the pointy ears as an alternate universe Batman. He reprises his role from Batman and Batman Returns in a role that would have connected to the recently cancelled Batgirl.

What is the plot of The Flash?

The official plot synopsis explains: "Worlds collide in The Flash when Barry uses his superpowers to travel back in time in order to change the events of the past.

"But when his attempt to save his family inadvertently alters the future, Barry becomes trapped in a reality in which General Zod has returned, threatening annihilation, and there are no Super Heroes to turn to.

"That is, unless Barry can coax a very different Batman out of retirement and rescue an imprisoned Kryptonian… albeit not the one he’s looking for.

"Ultimately, to save the world that he is in and return to the future that he knows, Barry’s only hope is to race for his life. But will making the ultimate sacrifice be enough to reset the universe?"

James Gunn has said that the film will reset much of the DCU timeline, which probably means kicking out the dead-weight of the universe, recasting certain faces and using science jargon to explain keeping certain actors.

Is there a trailer for The Flash?

Yes. The first trailer for The Flash dropped during Super Bowl 2023 giving DC fans their long-awaited first look at Ezra Miller as two incarnations as the character, Ben Affleck back as Bruce Wayne, Michael Shannon as Zod, Michael Keaton as Batman, and Sasha Calle making her debut as Supergirl.
