The film also marks Sasha Calle's debut as Supergirl and includes small roles for the likes of Unforgotten's Sanjeev Bhaskar and Derry Girls star Saoirse-Monica Jackson, both of whom appear as colleagues of Barry Allen/The Flash.

Read on for more information about the cast, including where you might have seen the main stars before, and details of all the cameo appearances (if you choose to scroll past the spoiler warning).

Ezra Miller plays Barry Allen/The Flash

Who is Barry Allen/The Flash? Barry is a police forensic investigator from Central City, and is also a member of the Justice League due to his ability to move at superhuman speeds with the use of the Speed Force. In the new film, Miller plays two different versions of the character – the one we know from the previous DCEU films and an alternate version from 2013.

What else has Ezra Miller been in? Miller first gained prominence for their acclaimed performances in films such as We Need to Talk About Kevin and The Perks of Being a Wallflower and went on to land big roles as Credence Barebone in the Fantastic Beasts films and Barry Allen in the DCEU. In recent years, they have been involved in multiple scandals including run-ins with the law, and in 2022 it was reported that they were receiving treatment for "complex mental health issues."

Michael Keaton plays Bruce Wayne/Batman

Who is Bruce Wayne/Batman? Generally speaking, this is a character who needs no introduction – the Caped Crusader has protected Gotham City from all sorts of villains in a huge variety of films. However, this version of the character hails from an alternate universe, with Keaton reprising his role from Batman and Batman Returns - only now 30 years older, disillusioned, and retired from crimefighting. Ben Affleck also reprises his role as Bruce Wayne/Batman in the early scenes before Barry arrives in the alternate universe.

What else has Michael Keaton been in? Keaton is perhaps still best known for his role as Bruce Wayne/Batman in Tim Burton's films, but he also has a number of other impressive credits to his name including Beetlejuice, Jackie Brown, and The Other Guys. He received a Best Actor Oscar nomination for his leading role in Birdman and also garnered acclaim for roles in Spotlight and The Founder. He made a return to superhero films when he played the main antagonist the Vulture in Spider-Man: Homecoming, while he recently had a starring role on Hulu limited series Dopesick.

She previously appeared as Iris in the Zack Snyder cut of Justice League, while she's also had roles in a number of TV shows such as Austin & Ally, Transparent, Easy, Angie Tribeca, and the upcoming Godzilla and the Titans.

The cast also includes: Antje Traue (Dark) as Zod's second in command Faora-U, Jeremy Irons (Dead Ringers) as Bruce Wayne's butler Alfred Pennyworth, Temuera Morrison (The Mandalorian) as Thomas Curry, Saoirse-Monica Jackson (Derry Girls) and Rudy Mancuso (Rim of the World) as Barry's co-workers Patty Spivot and Albert Desmond, Sanjeev Bhaskar (Unforgotten) as Barry's boss David Singh, and Brandon Field (Interview with the Vampire) as villain Al Falcone.

Meanwhile, there are also a number of high-profile cameos – but a number of these can be constituted as spoilers so tread carefully from here on.

The Flash cameos

Warning: Spoilers ahead for The Flash.
Throughout the film, there are a number of big-name cameos – starting with a brief appearance from Gal Gadot as Diana Prince/Wonder Woman at the beginning of the film, when she joins Ben Affleck's Batman and The Flash for the mission.
Most of the cameos are saved for the final act of the film, when Barry encounters various incarnations of popular DC superheroes in the Speed Force, many of them brought to the screen using AI and deep fake technology.

These cameos include Nicolas Cage as Superman – a role he almost played in the abandoned film project Superman Lives – Helen Slater as Supergirl, Teddy Sears as The Flash, Adam West as Batman and the late actors George Reeves and Christopher Reeve as Superman.

Another major cameo occurs after Barry returns to his timeline and reunites with Bruce. Of course, he is expecting to encounter the Ben Affleck version he had previously teamed up with, but instead finds yet another iteration of the character – the George Clooney version from Batman & Robin.

And one final cameo is saved for the post-credits scene, which sees Jason Momoa reprise his role as Aquaman as he and Barry enjoy a night on the town – with the former appearing in a very inebriated state.
