Barry Keoghan, who is most notably known for playing George Mills inDunkirk, recently teased in his role in DC’sThe Batmanon social media. After suffering numerous pandemic-related delays, the Warner Bros. and DC film wrapped production earlier this year.

The Batmanwas directed by Matt Reeves(War for the Planet of the Apes) and is a reboot of the iconic film franchise. The film is set during the second year of the Dark Knight’s career of fighting crime and follows his battle with the serial killer known as the Riddler. The loaded cast includes Robert Pattinson as Bruce Wayne/Batman, Zoë Kravitz as Selina Kyle/Catwoman, Paul Dano as Edward Nashton/Riddler, Jeffrey Wright as James Gordon, and Colin Farrell as Oswald “Oz” Cobblepot/Penguin. In 2017, it was announced that Ben Affleck would no longer be starring and directing the upcoming Warner Bros. project. Unlike Affleck’s Batman, Pattinson’s Caped Crusader will not be a part of the DCEU.

Keoghan took to social media to sharea behind-the-scenes photo fromThe Batman. In 2020, the 28-year-old was cast as Stanley Merkel, a Gotham City cop who was James Gordon’s partner in the comics. The character was created by Frank Miller and first appeared in 1986’sDark Knight #1. Merkel frequently helped Gordon track down the Dark Knight and inBatman: Dark Victory #6, he was found dead on St. Patrick’s Day.

Keoghan’s Merkel could play an important role in the upcomingHBO MaxThe Batmanspin-offGotham PD. The series will reportedly have the same gritty tone as the film and will focus on James Gordon and the Gotham City Police Department. Joe Barton (Giri/Haji) took over showrunner duties following Terence Winter’s exit last November. Reeves previously stated thatGotham PDwill serve as a prequel to the film and will be set in the Batman Year One period. Barton noted that it will examine the corruption in Gotham City and is told from the POV of a dishonest cop.

The Batmanisn’t the only big-budget film Keoghan is slated to star in. The Irish actor will next be seen as Druig in Marvel’sThe Eternals. The blockbuster was directed by recentOscar winner Chloé Zhao(Nomadland) and follows a group of superheroes that must reunite after staying hidden for thousands of years.

The film is part of Phase Four of the MCU and is expected to be released in the theatres this November.
