The Flash featured a stacked cast of DCEU mainstays and surprising cameos from unexpected actors.
Despite the movie's low box-office performance, the Ezra Miller-led DC movie's star-studded ensemble is still considered by many as one of its bright spots.
Every Actor & Character in The Flash Movie
1.) Ezra Miller - Barry Allen/The Flash
Ezra Miller reprised his role as Barry Allen (aka The Flash), the Scarlet Speedster, Central City's protector, and a founding member of the Justice League.
After not being ready to let go of the past, Barry decided to travel back in time to save his mother from dying. In doing so, he ended up in an alternate 2013 during the day when he originally received powers.
Aside from portraying the DCEU's main Barry Allen, Miller also plays his other self from the alternate timeline, the one who eventually became the Dark Flash.
After saving the multiverse from imploding, Barry restored the timeline while also coming to terms with his mother's death. However, the ending implied that he ended up in another alternate universe after George Clooney's Bruce Wayne showed up to meet him.
2.) Michael Keaton - Bruce Wayne/Batman
Michael Keaton made his return as Bruce Wayne (aka Batman). The actor reprises his Dark Knight role after his last portrayal of the character in 1992's Batman Returns.
In the alternate 2013 where the main Barry ended up, Keaton is that universe's Batman, but he already retired. Despite being hesitant to help the two Barry Allens, Bruce agreed to team up with them to try and find Superman and ultimately defeat General Zod and his forces.
Due to the overwhelming number of evil Kryptonians, Bruce decided to sacrifice himself in the end to save his Earth from them.
3.) Sasha Calle - Kara Zor-El/Supergirl
Sasha Calle made her DCEU debut as Kara Zor-El (aka Supergirl), the Kryptonian who ends up on Earth in younger Barry's alternate 2013.
In The Flash, a Russian mercenary group managed to detain Kara in Siberia for years before the two Barrys and Bruce helped her escape. In doing so, the character was able to regain her powers and join them in the fight against General Zod.
During the clash with Zod, the villain told Kara that he killed an infant Kal-El while also revealing that the Codex is within her blood. Supergirl was eventually murdered by Zod, successfully retrieving the Codex.
4.) Michael Shannon - General Zod
Michael Shannon reprised his Man of Steel role as General Zod, returning to wreak havoc in an alternate 2013 where Superman was killed by him when he was an infant.
General Zod's role in The Flash was quite similar to his antagonistic presence in Man of Steel. The only difference was the fact that he went up against two speedsters, Batman, and Supergirl instead of Henry Cavill's Superman during the climactic battle.
5.) Ron Livingston - Henry Allen
Ron Livingston played Henry Allen, Barry's father who was wrongly incarcerated in Iron Heights Penitentiary after being accused of killing his wife, Nora.
Henry gave a pep talk to Barry about letting go of the past, but he was not ready to do it.
Henry Allen served as Barry's emotional anchor, with him trying to do anything he could to prove his innocence. In the end, Henry was eventually freed from prison after Barry meddled with the CCTV of the grocery store in the past.
6.) Maribel Verdú - Nora Allen
Maribel Verdú played Nora Allen, Barry's mother who was killed by a mysterious murderer in the past.
Barry dedicated his life to uncovering the mystery behind Nora's death. However, in the end, Barry was able to accept her death with an emotional goodbye in the past.
7.) Kiersey Clemons - Iris West

Gal Gadot also made a brief appearance as Wonder Woman.
The DC heroine and Justice League member appeared at the last minute to save Batman and Al Falcone from falling off Gotham's bridge. Given that she used her Lasso of Truth to save them, it led to a funny (and honest) banter between her and Bruce.
11.) Saoirse-Monica Jackson - Patty Spivot
